Really Right Stuff 80mm Lever Release Clamp (B2-LLR II)

Effortlessly mount your camera plates, camera bars, and multi-purpose rails with the Really Right Stuff B2-LLR-II Lever-Release Clamp. Designed to be compatible with most Arca-type accessories, this clamp offers quick and easy top-loading functionality with its wide-opening jaws.

The locking lever release mechanism can be effortlessly opened or closed using only finger force. Once the clamp is securely locked onto the plate, it provides a robust holding power of up to 50 lb. The top of the clamp features three counter-sunk sockets, with the center socket equipped with female 3/8″-16 threads. It also accepts metric 6 and 1/4″-20 threaded screws via a bushing adapter when mounting to a ball head stem. Two additional 1/4″-20 threaded holes are positioned 45mm apart from the center socket, offering added flexibility for accessory attachment.

Crafted from CNC machined 6061-T6 aluminum, the clamp boasts a durable black anodized Type II finish. Laser-engraved index marks on both sides of the clamp ensure precise repeatability of positions. The low-profile stainless-steel locking lever is designed to hug the side of the clamp closely, minimizing the risk of snagging on clothing or other objects in the field. Additionally, the clamp incorporates a built-in bull’s-eye spirit level, allowing you to keep your camera leveled in a horizontal plane for optimal composition and accuracy.
