From entry-level hardware to certified professional rigging components – this range is built to help You achieve impressive results without compromising on safety.

What Is a Mount and Which Fixing Options Are There? Fundamentals

A mount is a device that securely fixes, supports or holds an object in a defined position. In everyday language You will also hear the terms bracket, holder, support, fixing, clamp or suspension – they all describe hardware that transfers a load from one component to another.

In event technology, mounts and fixings do far more than the generic wall brackets You know from home or IT setups. They connect lighting fixtures, effect devices, speakers and displays to truss, walls, ceilings or floors and must withstand dynamic loads, vibration and repeated rigging cycles.

Common fixing methods

• Wall mounting – brackets and side holders fixed to solid walls with dowels and screws.
• Ceiling suspension – suspension points and drop bars for permanent overhead installs.
• Clamp mounting – hook clamps, half-couplers and pipe clamps that grip round truss or barrel tubes.
• Floor fixing – base plates and foot mounts for uprights and towers.

How event fixings differ

Unlike consumer brackets, professional stage fixings carry a defined working load limit (WLL), are made from load-rated steel or aluminium and are designed for secondary securing with safety cables. This distinction matters: a domestic TV bracket is never a substitute for a rated truss clamp when a moving head hangs above an audience.

Types and Variants of Mounts and Fixings in Our Range

Our range covers the full spectrum of mounts and fixings used in stage, event and trade fair construction. Choosing the right type depends on what You mount, where You mount it and how heavy the load is.

Clamp mounts

• Hook clamps (truss clamps) – the classic C-shaped clamp that hooks over a truss tube and locks with a wing nut or bolt. Ideal for lighting fixtures.
• Half-couplers – single-tube clamps for fixing a fixture, bar or accessory to one round tube.
• Double couplers and swivel couplers – connect two tubes at fixed or variable angles for building grids and rigging bridges.
• Screw and spring clamps – for lighter, temporary fixings.

Connectors and spigots

• Spigot connectors (conical couplers) join truss segments and adapt fixtures to truss endpoints.
• Half-conical couplers with pins provide the certified structural connection between truss lengths.

Brackets and holders

• Wall brackets and side holders for permanent installations in clubs, theatres and churches.
• Base plates and foot mounts for stabilising uprights and towers.
• Pipe clamps for cable trays, barrels and drop bars.

Safety hardware

• Safety cables (steel wire bonds) as mandatory secondary suspension for every overhead load.

Fixings for Truss Systems: Matching Tube Diameters (35/50/60 mm)

One of the most important compatibility topics in event rigging is the tube diameter. A clamp only holds securely when its opening matches the truss tube it grips – and generic household hardware simply does not fit professional truss.

Our Naxpro-Truss systems use clearly defined tube diameters, so You can select clamps and fixings with confidence:

Why the diameter matters

A 50 mm coupler will not close correctly around a 35 mm tube, and forcing a 60 mm clamp onto a 50 mm chord leaves dangerous play. Always confirm the tube diameter of Your truss before ordering fixings – it is the single most common mistake when mixing components.

Practical tip

Most professional hook clamps are rated for the 48–51 mm range, covering the 50 mm chords of FD and HD truss. For 35 mm FD21 systems and 60 mm GS94 structures You need dedicated clamp sizes. When in doubt, contact us as Your reliable partner and we will match the correct fixing to Your truss.

Load Capacity, WLL and Safety Norms (DGUV V17, EN 1090)

Load capacity is the decisive selection criterion for any overhead fixing. The relevant value is the working load limit (WLL) – the maximum static load a component may carry with the required safety factor already applied. Never confuse WLL with break load: a clamp may fail long before its theoretical breaking point if You ignore the WLL.

Key figures to check

• WLL of the clamp or coupler – printed or embossed on professional hardware, from a few kilograms for light fixtures up to several hundred kilograms for heavy couplers.
• Point load of the truss – the truss itself has its own load table depending on span and configuration.
• Total rig weight – add fixtures, cabling, cases and accessories.

Relevant safety norms

Professional stage rigging in Germany falls under DGUV Vorschrift 17 (formerly BGV C1) for events and productions. Structural steel components follow EN 1090, and many LTT truss and rigging products carry TÜV SÜD verification and statical documentation.

Secondary suspension

Every load rigged above people legally requires a secondary securing – typically a rated safety cable that catches the load if the primary fixing fails. This is not optional: it is a core safety requirement that no consumer-oriented shop addresses, but every event technician must observe. Choose Your fixings with an honest safety margin and document Your rig.

Application Scenarios: Stage, Trade Fair, Lighting and Effects

Mounts and fixings appear everywhere in professional event technology. Understanding the application helps You pick the right hardware for the job.

Stage and concert

On stage You suspend moving heads, wash lights, LED bars and line arrays from truss grids. Hook clamps carry the fixtures, couplers build the structure, and safety cables secure every element overhead. The right mount lets You put Your show in the spotlight while keeping the audience safe.

Trade fair construction

At trade fairs, fixings hold displays, banners, spotlights and headers on lightweight truss booths. Here quick-fix elements and half-couplers speed up build-up and tear-down, because time on site is always tight.

Lighting and effect devices

Moving-head mounts, omega brackets and clamps position Your lighting precisely. For effect devices such as haze and fog machines, dedicated brackets let You rig the unit safely at height so the output spreads evenly across the stage.

Speakers and line arrays

Line-array flying frames and speaker brackets transfer heavy audio loads to rated suspension points – a professional application that demands correctly rated hardware.

Permanent vs temporary

Temporary event rigs prioritise fast, tool-light clamps, while permanent installs in clubs, theatres and churches use fixed wall brackets and ceiling suspensions. To complete Your setup, explore our lighting, effect and truss categories.

How to Attach a Mount Safely to Wall, Ceiling or Truss

Attaching a mount safely follows the same core principle everywhere: transfer the load into a structure that can carry it, then secure it a second time.

Mounting to a wall

1. Check the wall substrate – solid masonry or concrete only for load-bearing fixings.
2. Select dowels and screws rated for the load; never rely on plasterboard for heavy fixtures.
3. Mark and drill precisely, insert the dowels and fix the bracket level.
4. Verify the seating and test with a controlled load before final use.

Mounting to a ceiling

Ceiling suspensions must anchor into structural elements. Use rated eye bolts or suspension points, and always add a safety cable for overhead loads.

Mounting to truss

1. Confirm the tube diameter (35/50/60 mm) matches Your clamp.
2. Hook the clamp over the tube and tighten the bolt or wing nut firmly.
3. Attach the fixture to the clamp.
4. Fit a safety cable around the truss and through the fixture as secondary suspension.

Golden rule

Never exceed the WLL, always secure overhead loads twice, and document heavy rigs. When precision and safety both matter, correct mounting delivers reliable, repeatable results.

Buying Guide: Choosing the Right Fixing for Your Setup

This buying guide helps You choose the right mount or fixing without guesswork. Work through the criteria in order.

1. Define the load

Add up the weight of everything the fixing carries and compare it against the WLL – with a comfortable safety margin. Underrating the load is the most dangerous mistake You can make.

2. Match the structure

Determine whether You mount to a wall, ceiling, floor or truss, and for truss check the exact tube diameter (35/50/60 mm).

3. Choose the material

Steel offers the highest load capacity for heavy couplers; aluminium keeps lightweight brackets manageable; stainless steel resists corrosion for outdoor and permanent installs.

4. Professional vs entry-level

For overhead rigging above people, always choose certified professional hardware with a documented WLL. Entry-level clamps are fine for ground-supported or decorative use only.
