The R-LOCK feature in the clamp is a 5mm pin that mates with corresponding R-LOCK holes in the rail. The pin is spring-loaded to automatically engage the R-LOCK holes or be pushed down by non-R-LOCK rails, making it compatible with a wider range of “arca-type” rails. The user also has the option to disengage the pin at their discretion for rapid re-positioning. Note: Removing the R-Lock butterfly latch and index pin will allow for similar function as the Gen 1 Anvil.

The Anvil-30 ARC Ball head is purpose-built for heavy equipment support from the ground up. We added our patent-pending dual clamp system able to clamp both the RRS Dovetail standard and Picatinny rails in the same unit. We also removed extra knobs/adjustment settings under-utilized in the industry. The Anvil-30 ARC is as rigid as a leveling base but articulates like our popular photography ball heads while minimizing the limitations of each system. We designed this as a lightweight setup and realized its heavy duty potential.


  • R-Lock R-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 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 R-LOCK is engaged.
