Defender Defender 3 Er

An essential component to complete the Defender 3 system

The Defender 3 ER is the finishing accessory that completes a Defender 3 cable routing path. Positioned at the end of the line, it creates a smoother transition between the floor and the protector, providing a cleaner look and safer movement on stage, at exhibitions, in warehouses, or in assembly zones.

Who is it for and what are its uses?

This cable exit is intended for sound, lighting, and video teams, technical service providers, municipalities, and industrial environments that want to secure a passage while maintaining neat and professional cable routing.

Designed for safety and continuity of passage

Thanks to its connector and end shape, the Defender 3 ER ensures a reliable junction with series elements and reduces snags at the edges. Its robust design and ribbed surface make it a suitable choice for high-traffic areas.
