Product Details

Empower your photography with compact precision tailored for lightweight mobility

The RRS® B2-40-LR Clamp

Engineered for lightweight travelers and minimalist photographers who demand quick, secure gear swaps without added bulk, the B2-40 LR delivers compact performance ideal for on-the-go adventures.

Ultra-Compact 50mm Jaw Length for Lightweight Setups

Perfect for travel photographers and hikers with minimalist rigs, this slim clamp minimizes bulk while delivering secure performance for mirrorless systems.

Seamless Arca Compatibility with RRS Precision

This clamp features an integrated Arca-style dovetail for widespread compatibility with industry-standard quick-release plates, while adhering to the precise 1.5" RRS Dovetail Standard for the strongest, most secure clamp-to-plate connections available.

Rapid Lever-Release with Effortless Top-Loading

Patented lever enables instant, finger-force gear swaps and one-motion top-loading for quick plate insertion from above, boosting your efficiency through extremely fast gear transitions.

Multi-Surface Clamp with BH-25 and B2-40-LR

Enhanced R-Mount Rosette for Superior Strength and Flexibility

This updated rosette design replaces traditional tongue-and-groove connections to withstand extreme torque from long precision rifles, preventing bending or shearing at the clamp interface while also offering precise alignment options every 22.5 degrees.
As of 2020, all clamps feature an updated attachment style and will not sit flush with older ball heads. To resolve this, utilize our clamp rosette adapter.

Laser-Engraved Scale for Consistent Positioning

Easily visable markings allow precise, repeatable plate alignment for enhanced consistency in macro, studio, and panorama work.

Enhanced Safety with Visual Lock Indication

The lever's three-position design (closed, half-open, fully open) provides immediate visual feedback on your clamp's status, giving you confidence in your rapid gear swaps.

Low-Profile Lever Prevents Snags

The sleek, contoured lever hugs the clamp body closely without protruding, reducing the risk of catching on clothing, straps, or terrain, enhancing equipment safety in rugged outdoor conditions.

Elevate your support system with American-made mastery

The often imitated, but never duplicated speed and security of our industry-leading Arca-style lever clamps before your next adventure!

This clamp has given me the ability to use my RRS bracketed cameras on my new video tripod. It is worth the money to use Swiss Arca brackets.
High qualityclamp.
