- Made of zinc-plated plated steel.
- For use with strain relief bushings when...
- the panel is too flexible to support UL's 35-pound strain relief pull-out test.
- the panel is thin relative to the strain relief's locking slot. The backup washer eliminates "play".
- May also be used to contain the strain relief bushing in U-slot openings.
