Overview

Why should you invest in a quick-release system? Because screwing your camera or lens onto a platform with standard 1/4"-20 screw is tedious and insecure. Not only is it a hassle to screw your gear onto that platform, but once installed the camera or lens is free to rotate; there's nothing to prevent it from coming loose. Why invest your money in a tripod and tripod head only to compromise your shots with an insecure connection between camera and head? Instead, adopt the Really Right Stuff quick-release system.

The Really Right Stuff quick-release system is based on the Arca-Swiss standard and has two parts: a quick-release clamp and a quick-release plate. You always need both pieces of the system. The clamp will stay on your tripod head/accessory all the time, and the plate will stay on your camera all the time. You will need to purchase a separate quick-release plate for each camera or collared, telephoto lens that you want to mount in the quick-release clamp on your tripod head.

Clamp jaws open and close in one of two ways: by twisting a knurled knob on our tried & true screw-knob clamps; or by flipping a single lever on our innovative, patented lever-release clamps. The graceful Stainless Steel S-shaped cam-locking lever provides desirable benefits over traditional screw knob clamps.

This clamp has a NON-threaded center socket with countersink; mounting screw drops through from above into tapped female socket. This clamp cannot spin onto a threaded post. B2-40 LR mounts on Really Right Stuff ball heads, current model Arca-Swiss ball heads*, and some Manfrotto heads**.

*Some of the most recent Arca Swiss ball heads have clamps that cannot be removed by the consumer, such as the newest Z1. Please check your model to verify you can swap clamps or consult our knowledgeable Customer Support Representatives for compatibility.

**Disclaimer - Really Right Stuff LLC. is not responsible for damaged products due to forcing the wrong thread screw into products. Really Right Stuff ball heads utilize the 1/4-20 screw while other brands may use the M6 screw. If you need help determining compatibility, feel free to call our customer service department at (385) 248-0777 or toll-free U.S. & Canada at (888) 777-5557.

Features

Easy Top-Loading: In one quick action, the clamp can go from closed to fully open, allowing easy top-loading of Arca-Swiss-compatible quick-release camera and lens plates. No more lost shots while fumbling to feed the plates into the end of the clamp.
Visual Confirmation of Lock Position: You can readily observe if the lever is locked, half-open or fully open.
Low Profile: The lever does not protrude above or below the top or bottom of the clamp, and, in the closed position, the lever closely hugs the contours of the clamp. This makes it less of a "weed catcher" in the field and reduces the chance of being damaged in a fall.
Less Abrasive, No Twisting: The smooth contours of the lever are less abrasive than standard knurled knobs, and for those with arthritic hands, the graceful lever cams open and closed with just finger force.
Super Tough, Reliable: The Stainless Steel lever delivers a lifetime of wear and rides on a self-lubricating, wear-resistant bronze bearing surface. Delivers 50 lbs. of holding power under full compression (the fully closed position) with our plates. This is more than sufficient for any practical photographic application.
