Safety Wires

Safety wires for stage, lighting, and event installations

Safety wires are an important part of any professional lighting and stage setup. They are used as extra fall protection when lamps, lighting effects, speakers or other equipment are mounted at height on truss, ceiling brackets, stands, or rigging systems. The purpose of a safety wire is to prevent equipment from falling if the primary mounting fails, thereby reducing the risk of personal injury and material damage.

In the event, concert, and installation industry, the use of safety wires is standard procedure, and in many situations, it is a requirement when equipment is suspended over audiences or work areas.

What is a safety wire?

A safety wire is a strong steel wire with a locking mechanism, mounted as a secondary securing between the equipment and the supporting structure. If the primary hook, bolt, or bracket loosens, the wire will hold the equipment in place and prevent free fall.

Typically, a safety wire consists of:

• flexible steel wire
• protective coating or plastic cover
• integrated carabiner or lock
• defined maximum load

The construction of the wire makes it both strong, flexible, and quick to install in busy setups.

When are safety wires used?

Safety wires are used whenever technical equipment is mounted at height, where a fall could pose a risk. This applies to both temporary event setups and permanent installations.

They are used, among other things, for:

• stage lights and effect lamps
• moving heads
• LED PAR Cans
• projectors and AV equipment
• installations in truss systems
• mounting on tall lighting stands
• suspension from ceilings or beams

Even relatively light equipment can pose a serious hazard if it falls from a height, and therefore secondary securing should always be used.

Why are safety wires necessary?

Primary mounting brackets can occasionally fail due to incorrect installation, vibrations, wear, material defects, or accidents during setup. The safety wire acts as a backup and reduces the consequences if this happens.

The use of safety wires contributes to:

• increased personal safety
• protection of expensive equipment
• compliance with safety procedures
• more professional installation

In professional productions, it is generally not considered optional but a fixed part of proper rigging.

Choosing the correct safety cable

When choosing a safety cable, it is important to check the maximum load and ensure that the cable is correctly sized in relation to the equipment's weight. The load rating must always exceed the actual weight of the mounted equipment.

You should especially pay attention to:

• maximum load in kg
• cable length
• type of locking mechanism
• cable thickness
• quality of carabiner or lock

A correctly sized cable provides both better safety and more stable mounting.

Correct installation of safety cable

To achieve optimal protection, the safety cable must be installed correctly. The cable should always be attached directly to the supporting structure and not just to the same bracket as the primary mounting.

General recommendations:

• attach the cable to a solid supporting structure
• keep the cable as short as practically possible
• avoid loose, long slack loops
• check the lock before use
• inspect the cable regularly for wear

A correctly installed cable will typically have only minimal extra length, so the fall height is minimized as much as possible.

Safety cables for both mobile events and permanent installations

Safety cables are used in both mobile setups, where equipment is frequently set up and taken down, and in permanent installations in cultural centers, clubs, theaters, and conference rooms. Their simple installation makes them a quick, effective, and economical safety solution.

Even in smaller setups, safety cables should be used consistently, as the extra security takes only a few seconds to install but can prevent serious accidents.

Find the right safety cable for your equipment

The right safety cable depends on the equipment's weight, mounting height, and type of installation. For smaller LED lights, a compact cable may be sufficient, while heavier moving heads or installations require stronger models with higher load capacity.

By choosing correctly sized safety cables and using them consistently in all suspended installations, you ensure a safer setup for both the audience, staff, and equipment.
