RRS-LOCK engages effortlessly with a 5mm steel pin, ensuring a snug fit for RRS-LOCK-equipped rails/plates. Enjoy ambidextrous operation with the butterfly latch and lever. Plus, adjustable tension makes ARC-LR compatible with a wide range of 3rd-party Arca-Swiss style quick release plates. It's the epitome of precision and versatility in a clamp.
