Designed for creators building custom rigs with multi-purpose Arca rails
The RRS® B2-FAS Sliding Lever Clamp
The B2-FAS offers adjustable fore/aft sliding for precise quick-release positioning in diverse applications.

Double-Sided Mounting for Stacked Configurations
Clamps two Arca-style plates or rails simultaneously in a perpendicular orientation, ideal for making smooth mounting point adjustments in custom rigs without disturbing the overall setup, ideal for creators fine-tuning complex configurations.
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.
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.
