Lighting wing limiter EUROLITE THA-450F black — safety device for truss and rigging

The EUROLITE THA-450F black is a wing limiter engineered for lighting rigging and truss installations. Designed as a passive safety device, it controls the lateral movement and travel of suspended fixtures on trusses and wire systems used in stage, concert and event environments. The unit helps reduce the risk of overtravel and accidental collisions by physically limiting the range of motion of lighting fixtures attached to a truss or rigging wing.

Advantages

Made for compatibility with common truss profiles and rigging layouts, the EUROLITE THA-450F black provides a clear mechanical stop that is simple to install and inspect. Its compact, durable construction offers reliable performance under repeated use and in professional environments. The device contributes to safer rigging practices by providing a fixed limit point that reduces the likelihood of fixture damage and unintended displacement.

Suitable for

• Stage and theatre truss systems that require controlled fixture travel
• Concert and live-event rigging where lateral movement must be limited
• Rental and production companies needing standardized safety stops
• Installation points on wire-based or motorized suspension systems

Key specifications

• Function: mechanical wing limiter for lighting fixtures and truss wings
• Material: robust metal construction suitable for professional use
• Finish: black protective coating to reduce visible wear
• Mounting: designed for attachment to standard truss elements and rigging points
• Operation: passive stop that limits lateral travel of suspended fixtures

How to use

Position the EUROLITE THA-450F black at the desired limit point along the truss or rigging wing and secure it according to the truss manufacturer’s recommended fastening method. Ensure the device is aligned so that the moving part of the fixture contacts the limiter at the intended position and that all fasteners are tightened to specified torque values. After installation, perform a slow movement test of the fixture to confirm that travel is limited correctly and that there is no unintended interference with adjacent equipment.

Usage recommendations

Inspect the limiter regularly for signs of deformation, corrosion or loose fittings and verify mounting integrity before each event. Use the EUROLITE THA-450F black in combination with appropriate load-rated hardware and follow all local safety standards and the truss manufacturer’s guidelines when installing and using any rigging limit device.
