Allied offers a patented, non-metallic wire clamping system that automatically locks your wire in place for a secure hold. No screws to loosen and tighten makes wiring faster and easier saving time on installation. The Speed "K" Klamp allows the wire to be inserted through the knockout and the memory retaining feature of the clamp prevents wire from being pulled back from the box.

Should a knockout be inadvertently opened and not used, the Speed "K" Klamp is considered sufficent closure of the opening per UL.
