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.

Easy Top Loading

The top loading clamp can go from closed to fully open in one quick action of the quick release lever, allowing speedy mounting of Arca-Swiss compatible quick release camera and lens plates.

Visual Lock Confirmation

You can tell at a glance if the quick release lever is fully open, half-open, or locked

Low Profile Design

The quick release lever does not protrude above or below the top or bottom of the clamp. In the closed position it closely hugs the contours of the clamp, reducing the chance of being damaged.

Provides precise and repeatable plate alignment

I want to put this clamp on my inexpensive Canon aluminum monopod for a safer and quicker Arca Swiss connection to a footed Canon RF 100-500. But can I get it mounted on the Canon monopod?
Asked by: John
The clamp uses a 1/4-20 screw for fastening to ball head or tripod so the tripod must have a threaded 1/4-20 hole for attachment. The clamp is not threaded.

Asked by: Richard
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. You would need to check the specific head you have to see if it has this connection. Not all Manfrotto heads are the same.
