Lever-Release style quick-release clamp with 3/8"-16 mounting socket

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 the 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 RRS 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 and 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.

The B2 LR II has dual mounts: center socket is countersunk on top but also threaded 3/8"-16. Mount by spinning onto an exposed threaded 3/8" post or with flat head screw from above (accept M6 or 1/4"-20, not 3/8"). These clamps are appropriate for mounting on:
  1. Any head or platform with exposed 3/8"-16 threaded post can drop onto a female socket tapped 1/4"-20 (for any RRS head) or metric 6 (for all others; all screws sold separately)
  2. Any head or platform with exposed 1/4"-20 threaded post - install a reducer bushing into the socket hole of the clamp
  3. Any head or platform with 3/8"-16 female socket

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 50lbs of holding power under full compression (the fully closed position) with our plates; this is more than sufficient for any practical photographic application

    The ultimate compact lever release clamp

    by Brad M - | 3/27/2020 7:43 pm

    This clamp makes a perfect pairing with a Gitzo GM4552L monopod and Wimberly MH-100 MonoGimbal head for a very compact, lightweight but robust setup in the field. I couldn't be happier with the usual quality, fit and finish of this RRS release clamp.
