What Are Truss Accessories? Fundamentals and Function

Truss accessories are the connecting, mounting and safety components that complement aluminium and steel truss profiles. While a truss profile carries the load, accessories join the individual elements, attach equipment and secure the whole construction against failure. Without them, even the strongest profile stays a single, unusable piece.

The most fundamental group are connectors: conical connectors, half cones and conical pins that slot into the tube ends and are locked with bolt and split pin — or, on request, with bolt and nut. These push-fit connections make truss systems fast to assemble and just as fast to dismantle after a show.

The second group are mounting parts: couplers, clamps, hooks and adapters that let you hang lighting fixtures, banners, speakers or video walls onto the chords of a truss. A third group covers rigging and safety accessories such as hanging points, shackles, steel wire ropes and safety cables.

How truss accessories differ from truss profiles

It is important not to confuse accessories with the truss itself. A truss (1-point, 2-point, 3-point or 4-point) is the load-bearing framework; accessories are the smaller parts that connect, mount or protect it. Because different truss series vary in tube diameter and wall thickness, accessories are always series-specific — a connector for an FD21-24 system does not fit an FD31-44 chord.

Connectors, Couplers and Clamps: How Truss Elements Are Joined

Joining truss elements correctly is the core task of every accessory range. LTT stocks all the fixing types you need for a safe, code-compliant build.

Connectors for joining chords

The standard way to link two truss segments is the conical connector. It is driven into both tube ends and secured with bolt and split pin, the classic locking method in event rigging. Half cones and conical pins offer alternatives for specific series and applications. On request, LTT also supplies bolt-and-nut fixings where a fully tightened, permanent joint is preferred.

Couplers for hanging loads

Couplers attach loads to the round chords of a truss. The range covers half couplers, narrow couplers, fixed couplers and swivel couplers, so you can rig at any angle. Swivel couplers rotate freely, while fixed couplers hold a load rigidly in place.

Clamps, hooks and half clamps

Clamps, hooks, half clamps and double clamps mount lighting fixtures, banners, audio systems and video panels directly onto the truss. Double clamps join two profiles side by side; half clamps grip a single tube. Each product page states which truss series and tube diameter the part fits, so you always match the correct component.

Adapters and quick connections

Adapters extend what a truss can carry — they hold eye bolts, receive crank stands or provide quick click connections for fast, tool-light assembly. For creative or non-standard builds, adapters bridge the gap between the standard system and your individual idea. Explore the full selection to find the optimal solution for your rig.

Types and Variants of Truss Accessories

The accessory range breaks down into clearly defined types, and knowing them helps you order faster.

• Connectors: conical connectors, half cones, conical pins, bolt-and-split-pin sets, bolt-and-nut sets and complete connector sets.
• Couplers: half, narrow, fixed and swivel couplers for hanging loads at any angle.
• Clamps and hooks: clamps, hooks, half clamps and double clamps for mounting fixtures and equipment.
• Adapters: eye-bolt adapters, crank-stand receivers and quick click connections for special constructions.
• End and cap parts: end plates, base plates and glass-pane holders that finish off a build.
• Rigging and safety parts: hanging points, shackles, steel wire ropes and safety cables.
• Transport accessories: truss rolling boards, transport cases and storage supports.

Each variant is designed for a defined load range and truss series. Because a swivel coupler behaves differently from a fixed one, and a half clamp carries less than a double clamp, always check the stated working load limit before you buy. This way you achieve impressive results without over- or under-specifying your rig.

Comparison: Connector Types and Fixing Methods

Choosing the correct fixing method is a frequent point of uncertainty. The comparison below shows the main differences between the most common truss connectors and locking methods, so you can decide which one suits your build.

As a rule of thumb: for touring and event work where fast build-up and tear-down matter, the conical connector with bolt and split pin is the professional standard. For semi-permanent or fixed installations where the structure stays in place, bolt-and-nut fixings give a rigid, tamper-resistant joint. Always follow the manufacturer's assembly instructions for the exact truss series you use.

Technical Buying Criteria: Material, Diameter and Working Load Limit

Selecting truss accessories is a technical decision, not a guess. The key criteria below let you match parts precisely to your system.

Tube diameter and wall thickness per Naxpro series

Naxpro-Truss systems differ clearly in dimension, and accessories are cut to fit:

• FD21-24: 35 mm tube diameter, 2 mm wall thickness.
• FD31-44: 50 mm tube diameter, 2 mm wall thickness.
• HD31-44: 50 mm tube diameter, 3 mm wall thickness (heavy-duty).
• GS94: 60 mm tube diameter, 5 mm wall thickness, with 40 x 3 mm diagonal tubes.

An FD21-24 clamp will not fit a 50 mm chord, so always confirm the diameter before ordering.

Working Load Limit (WLL)

Every clamp, coupler and hanging point has a defined Working Load Limit — the maximum load it may safely carry in normal use, with a built-in safety factor. Never load an accessory to its breaking point; the WLL is the figure that counts. When you distribute lights, speakers or banners across a truss, sum up the loads and keep them well within the combined WLL of the mounting parts and the truss itself.

Material and finish

Most professional truss accessories are made from high-grade aluminium alloy or steel. Steel parts (couplers, shackles, wire ropes) handle the highest loads, while aluminium parts save weight. Check that the finish resists corrosion for outdoor use.

Buying Guide: Which Accessory for Which Build

This buying guide gives you structured selection help based on the kind of construction you are planning.

For a truss bridge or lighting bar

A horizontal bridge between two supports mainly needs conical connectors to join the segments and half or double clamps plus swivel couplers to hang your fixtures. Check the WLL against the total lighting weight.

For a tower or ground support

Towers and ground support rigs carry vertical and lifting loads. Here you need hanging points, shackles and often a lifting motor with steel wire ropes. Base plates stabilise the foot, and safety cables act as a secondary attachment.

For a stage roof

A stage roof combines a ground support with a roof grid. Beyond connectors and couplers, you will need weather-resistant fixings, adequately rated hanging points and secure load distribution across all corners.

For a trade fair stand

Trade fair stands use truss both structurally and decoratively. Clamps, adapters and glass-pane holders let you mount banners, screens and shelving cleanly. Quick click connections speed up on-site assembly.

When in doubt, note your truss series, list every load you want to hang and match each accessory to the stated diameter and WLL. If your project needs something beyond the standard range, LTT's own planning department can develop custom special constructions.

Rigging and Safety: Hanging Points, Shackles and Load Limits

Rigging accessories are where safety becomes non-negotiable. When you suspend a truss above people, every component in the load path must be rated and inspected.

Hanging points and shackles

Hanging points are dedicated attachment fittings that let you lift or suspend a truss with chain hoists or steel wire ropes. Shackles connect ropes, slings and points into a continuous, load-rated chain. Each part carries a stamped Working Load Limit — never mix rated and unrated hardware.

Steel wire ropes and safety cables

Steel wire ropes (Anschlagmittel) transfer the load to lifting motors, while safety cables provide the mandatory secondary suspension for any fixture or component hung overhead. A safety cable catches a load if the primary attachment fails.

Load limits are the deciding factor

Rigging safety always comes back to the WLL. Add up all suspended loads, respect the lowest-rated element in the chain and keep a clear safety margin. The LTT Riggatec range covers hanging points, shackles, wire ropes and safety cables designed specifically for professional truss rigging. Correctly rated rigging accessories are what make overhead loads safe — treat every hanging point as a life-safety component.

Standards and Compliance: DGUV Vorschrift 17, EN 1090, TÜV SÜD and CE

Working with truss and rigging accessories is governed by clear German and European rules, and knowing them positions you on the safe side.

DGUV Vorschrift 17 (formerly BGV C1)

DGUV Vorschrift 17 (previously known as BGV C1) is the German accident-prevention regulation for stages and production sites. It sets requirements for load-bearing structures and overhead suspension in the event industry, including inspection and documentation duties.

EN 1090 and structural certification

EN 1090 is the European standard for the execution of steel and aluminium structures. Truss produced to EN 1090 has documented, verifiable load capacity — an important basis when static calculations are required for a build.

TÜV SÜD and CE marking

Many truss accessories are TÜV-tested and carry the CE marking, confirming that they comply with the applicable directives and current DIN standards. When you build load-bearing structures, use only certified, load-rated components and keep the accompanying documentation for your safety records. As a compliance-aware specialist, LTT supplies parts that meet these professional requirements.

Application Scenarios: Stages, Trade Fair Stands, Towers and Ground Support

Truss accessories prove their value across the full spectrum of event and exhibition work.

Stages and stage roofs

On stages, truss forms lighting grids, roofs and backdrops. Connectors join the grid, couplers and clamps hang the fixtures, and hanging points suspend the whole structure. For a stage roof, weather-resistant fixings and correctly rated points are essential to create a reliable, impressive result.

Trade fair stands

In the trade fair sector, truss is both structure and eye-catcher. Clamps, adapters and glass-pane holders mount banners, screens and product displays, letting you set your brand in scene on the show floor.

Towers and ground support

Towers and ground support rigs lift lighting and audio to height. Here, base plates, hanging points, shackles and lifting motors work together to raise loads safely and hold them in position.

Rigging setups

Across all these scenarios, the same accessory families reappear: connectors to build, couplers and clamps to mount, and rigging parts to suspend. Matching the right components to each scenario is what separates a stable rig from a risky one — and LTT stocks the parts for every case.

Transport and Handling: Rolling Boards, Cases and Storage Accessories

Between shows, truss and its accessories need to move and be stored safely — and dedicated transport accessories make that far easier.

Truss rolling boards

A truss rolling board (Traversen Rollbrett) is a wheeled dolly that carries stacked truss segments through venues, up ramps and into trucks without manual lifting. Rolling boards protect your back and your profiles, speed up load-in and load-out, and keep heavy truss stacks stable during transport.

Cases and protective covers

Transport cases and covers shield connectors, clamps, couplers and small rigging parts from damage, dust and loss. Because small accessories are easy to misplace, organised cases keep every pin, bolt and coupler where you need it on site.

Storage supports

Storage racks and supports keep truss off the floor and free of deformation between jobs. Well-stored aluminium truss stays true and lasts longer, which protects your investment over years of professional use.

Brands and Manufacturers of Truss Accessories

LTT is both a manufacturer with its own production in Germany and a full-service dealer, so you find house brands and leading third-party manufacturers side by side.

LTT house brands

Naxpro-Truss is the leading choice for truss systems and matching accessories, from conical connectors to hanging points. Riggatec covers rigging accessories such as shackles, wire ropes and safety cables. Litetruss and Junior Truss round off the LTT own-brand programme.

Leading third-party manufacturers

Alongside the house brands, LTT stocks accessories from established names including Global Truss, Prolyte, Alutruss and Duratruss. These are among the most widely used truss systems in the industry, and their accessory ranges are compatible within their respective series.

Cross-brand compatibility

A frequent question is whether accessories work across brands. As a rule, connectors and clamps are series- and diameter-specific, so a part designed for a 50 mm Naxpro chord may also suit another 50 mm system — but you must always verify diameter, wall thickness and manufacturer specification before mixing. When in doubt, stay within one system to guarantee a safe, code-compliant build.

Care and Maintenance of Truss Accessories

Truss accessories are safety-relevant hardware, so regular care and inspection are part of professional use.

Cleaning and inspection

After every job, wipe down connectors, couplers and clamps to remove dust, dirt and moisture. Check bolts, split pins and threads for deformation, corrosion or wear. A bent pin or a worn thread compromises the joint and must be replaced immediately.

Regular checks of rigging parts

Hanging points, shackles and steel wire ropes require particular attention. Inspect wire ropes for broken strands, kinks or corrosion, and confirm that stamped WLL markings remain legible. Under German rules, load-bearing rigging equipment is subject to periodic inspection — keep records of your checks.

Storage protects your parts

Store aluminium and steel accessories dry to prevent corrosion, and keep small parts organised in cases so nothing is lost. Careful maintenance keeps your accessories reliable and extends their service life across many productions.
