• RRS-LOCK™ 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 advantage of the System is the user has multiple “hard-stop” positions along the rail while retaining smooth edges and corners for maximum ergonomics and a snag-free interface that is inherently resistant to wearing down. 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 RRS-LOCK™ is engaged.
• 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; no more lost shots while fumbling to feed the plates into the end of the clamp
• Visual Confirmation of Lock Position: You can readily observe if the lever is locked, half-open or fully open
