Really Right Stuff PC-LR Round Lever-Release Style Panning Clamp, 2.8"

The PC-LR Panning clamp is designed to offer precision horizontal panning as a versatile built-in or modular accessory. Combining our patented lever-release clamp jaw with a lockable 360-degree panning bearing, the PC-LR is a robust yet lightweight panning solution for more convenient single-row panorama shooting.Like all of our lever-release clamps, the PC-LR offers the fastest action for quick-release of plates and rails in and out of the jaw. With a patented stainless-steel lever that flips to three positions: closed, half-open, fully-open - you can be confident in the state of the clamp at a glance.The PC-LR features a built-in dovetail base, allowing you to mount it onto any Really Right Stuff ballhead clamp. This allows using the ballhead itself to level the panning axis, thus eliminating the need for a leveling base in many applications. The increased speed and accuracy offered by the panning clamp makes setup for single-row panoramas a snap.When you're done shooting, just slip the panning clamp back into its neoprene pouch (included) and drop it in your camera bag. This quick-release modularity allows part-time panorama shooters to keep the weight off their tripod setup when it's not needed.For those who prefer not use the dovetail on the bottom, the clamp features a central 3/8"-16 threaded socket, and also includes cap-head 1/4"-20 and M6 screws for mounting directly to Really Right Stuff and Arca-Swiss ballheads.
