Really Right Stuff ARC-LR Adjustable R-LOCK Lever-Release Photo Clamp

After extensive design and engineering, the ARC-LR Adjustable R-LOCK Lever-Release Photo Clamp emerges as a game-changer in the world of photography equipment. This innovative product incorporates the Rapid-Lock (R-LOCK) System, a unique safety feature that enhances both the mounting rail and quick-release clamp, adhering to the RRS 1.5" Standard. The R-LOCK system boasts a "hard-stop" feature, a robust 5mm diameter steel pin that perfectly aligns with 5.5 mm diameter holes in the rail. This feature not only supplements the traditional friction-based clamping mechanism but also effectively prevents unintentional repositioning of the rail within the clamp when the R-LOCK is engaged.

The ARC-LR Adjustable R-LOCK Lever-Release Photo Clamp also features the R-Mount Interface. This rosette design is engineered to prevent twisting at the coupling point between the ARC-LR and RRS head over time. It also assists in eliminating any "play" that may result from regular use on our earlier tongue-and-groove designs. One of the standout features of this photo clamp is its easy top-loading capability. With one swift action, the clamp can transition from closed to fully open, facilitating effortless top-loading of RRS Dovetail and Arca-Swiss compatible quick-release plates. The ARC-LR Adjustable R-LOCK Lever-Release Photo Clamp also provides visual confirmation of the lock position.

Users can easily determine if the lever is locked, half-open, or fully open. For the first time, the ARC-LR allows users to adjust a RRS clamp's jaw tolerance. This feature enables the clamp to conform to some 3rd party Arca-style plates or rails, offering greater versatility and compatibility. In conclusion, the ARC-LR Adjustable R-LOCK Lever-Release Photo Clamp is a meticulously designed piece of photography equipment, offering enhanced safety, ease of use, and adaptability.
