Empower your photography with compact precision tailored for lightweight mobility
The RRS® B2-LR-II Clamp
Crafted for versatile photographers and videographers seeking reliable mounting across diverse setups, the B2-LR II combines precision leveling and high load capacity to support mid-sized gear in dynamic shooting environments.
Versatile 60mm Jaw length with Dual-Mounting Options
Equipped with a center 3/8"-16 threaded socket and two additional 1/4"-20 holes spaced 30mm apart, this clamp seamlessly integrates with a wide range of tripod heads, platforms, and accessories, offering flexible setup configurations for diverse shooting scenarios.


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.


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.


Integrated Bull's-Eye Spirit Level for Precision Leveling
Built-in bubble level helps you achieve a horizontal level in fewer adjustments, saving you time and frustration.
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!

I purchased this clamp to replaced the clamp on a competing brand's ball head. I do a lot of astrophotography so I need things to fit together well and without me having to fiddle around in the dark. This clamp when paired with the RRS L bracket is as good as it gets.
