Upgrade gear with ARC-LR, the RRS lever-release clamp featuring RRS-LOCK for seamless equipment use and adjustable tension.
ARC-LR is a new RRS lever-release clamp for photographers that features R-LOCK, a new feature designed to improve ease of use, expediate deployment of equipment, and provide an additional measure of securing one's kit.
The ARC-LR provides the certainty of auto-centering with both auditory and tactile feedback when your camera/lens plate is centered and locked within the clamp. R-Lock uses a 5mm steel pin to engage the R-Lock mounting divots (holes) when you load your R-lock equipped rail/plate into the clamp and slide it into position.
An ambidextrous butterfly-latch and lever allows the user to arrange the clamp to be operated according to the user's preference.
For the first time, ARC-LR represents a RRS lever-release clamp option with adjustable tension, providing compatibility with most 3rd-party plates and rails.
R-LockR-LOCK (short for Rapid-Lock) System adds unique safety-stop features which are built in to both a mounting rail and quick-release clamp that adhere to the RRS 1.5” Standard. The ”hard-stop” feature is comprised of a 5mm diameter steel pin that engages 5.5mm diameter holes in the rail. In addition to supplementing the traditional friction-based clamping mechanism, the interface prevents unintentional repositioning of the rail within the clamp when the R-LOCK is engaged.
R-Mount Interface: R-Mount’s rosette will prevent twisting at the coupling point between the ARC-LR and RRS head over time, and will assist in eliminating “play” that results from regular use on our earlier tongue-and-groove designs.
Easy Top-Loading:In one quick action, the clamp can go from closed to fully open, allowing easy top-loading of RRS Dovetail and arca-swiss compatible quick-release plates
Visual Confirmation of Lock Position:You can readily observe if the lever is locked, half-open or fully open
Adjustable Clamp Tolerance: For the first time, the ARC-LR allows users to adjust a RRS clamp's jaw tolerance to conform to some 3rd party Arca-style plates or rails.
