Really Right Stuff Round Lever Quick Release Clamp for Series 3 Leveling Base

Looking for a more secure option when it comes to just putting your camera onto a platform with a standard 1/4"-20 screw, then look no further than the Round Lever Quick Release Clamp from Really Right Stuff. The quick release system is based on the Arca-Swiss standard and is comprised of two parts. The quick release clamp and a quick release plate. The clamp will stay on your tripod head accessory all the time, and the plate will stay on your camera all the time. The stainless steel s-shaped cam-locking lever provides benefits over traditional screw knob clamps.

Replaces the traditional platform of the RRS Series 3 Leveling Base (TA-3-LB) and Series 2 Universal Leveling Base (TA-2U).

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.

Users can readily observe if the lever is locked, half-open, or fully open.

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.

The smooth contours of the lever are less abrasive than standard knurled knobs, and for those with arthritic hands, the lever cams open and close with just finger force.

The stainless steel lever sustains a lifetime of wear and rides on a self-lubricating, wear-resistant bronze bearing surface. It delivers 50 lb of holding power under full compression (the fully closed position) with plates.
