Product Details

ARC-LR RRS-LOCK® Arca Quick-Release Lever Clamp — 40 mm

Clamp Rosette Adapter and ball head interface cross section The ARC-LR is RRS’s RRS-LOCK® equipped lever-release clamp, designed to deliver rapid, repeatable clamping on 1.5" Arca-style rails with added safety and centering features. A 5 mm steel RRS-LOCK pin engages compatible rails to resist unintentional movement, while the ambidextrous butterfly latch and lever provide intuitive operation from either side. Adjustable tension allows you to tune the clamp to many third-party Arca-style plates, making this 40 mm clamp a versatile upgrade for ball heads, leveling bases, and custom support setups.

Note: As of 2020, all clamps feature an updated attachment style and will not sit flush with older ball heads. To adapt legacy heads, use the Clamp Rosette Adapter (sold separately).

Features

RRS-LOCK® system adds centered indexing and safety-stop engagement to compatible RRS 1.5" standard rails, using a 5 mm steel pin to help prevent unintentional movement.
R-Mount interface minimizes twisting and play between the ARC-LR and RRS heads for long-term stability.
Easy top-loading design enables quick transitions from closed to fully open positions for fast, hassle-free attachment from above.
Secondary latch increases security by helping prevent accidental lever opening during transport or use.
Visual lock indication gives instant confirmation of clamp status for added confidence.
Adjustable clamp tolerance accommodates many third-party Arca-style plates and rails for broader compatibility.

    Excellent quality. Easy to adjust. I like how the lock works perfectly with my RRS Sony A7RV L bracket.
