When it comes to securing your camera or lens, the B2-LR II 60mm Lever-Release Style Quick-Release Clamp from Really Right Stuff offers a durable, efficient, and reliable solution. This versatile quick-release clamp is designed to eliminate the tedious and insecure process of screwing your gear onto a platform with a standard 1/4"-20 screw. Instead, it offers a secure connection between your camera and tripod head, ensuring your shots are never compromised.Based on the Arca-Swiss standard, the Really Right Stuff quick-release system comprises two parts: a quick-release clamp and a quick-release plate. The clamp remains on your tripod head or accessory at all times, while the plate stays attached to your camera. For each camera or collared, telephoto lens you wish to mount, a separate quick-release plate is required.The B2-LR II 60mm Quick-Release Clamp features a patented lever-release design, offering a significant advantage over traditional screw knob clamps. With a single flip, the clamp jaws can transition from closed to fully open, facilitating easy top-loading of Arca-Swiss-compatible quick-release camera and lens plates. This eliminates the risk of missing shots while struggling to feed the plates into the end of the clamp.The lever-release clamp also provides visual confirmation of the lock position, allowing you to easily determine whether the lever is locked, half-open, or fully open. Its low-profile design ensures the lever does not protrude
