Really Right Stuff Lever Release Clamp

The rugged B2-40-LR Lever Release Clamp from Really Right Stuff is compatible with most Arca-type camera plates, camera bars, and multi-purpose rails. The jaws of the clamp open wide for plates to be top-loaded quickly and easily. The quick release locking lever opens or closes using only finger force, but still provides a robust holding power of up to 50 lb to any Arca-Swiss compatible quick release plate. The clamp features a threadless 1/4"-20 counter-sunk mounting socket, which accepts the included 1/4"-20 screw or metric 6 screw for mounting to a ball head stem or other device. Index marks are laser engraved on both sides of the clamp so a position can be repeated reliably. The stainless steel quick release locking lever has a low profile, which hugs the side of the clamp very closely to minimize the risk of damage.
