The RRS Cinch-LR (BA) Binocular Adapter provides quick-release functionality to your binocular/monocular of choice for housing diameter ranges between 1.77"-2.56". The adapter is precision CNC machined from a solid block of aircraft grade aluminum, designed and manufactured in Lehi, UT. 

The Cinch-LR BA is a semi-permanent clamp mount, that should fit in most supplied harnesses. The RRS 1.5" dovetail standard, coupled with the Manfrotto RC2 standard, should allow the majority of tripod users to quickly attach and detach their optic from multiple ball head manufacturers. 

If using a standard other than one of the two mentioned above, there is a 3/8"-16 mounting socket on the bottom of the Cinch-LR to adapt to a system of your choice. 

The Cinch-LR BA can be mounted perpendicular or parallel to the optical plane. The removable strap can be fed through the buckle with the excess strap exposed on the outside, or reversed with the excess following the contour of the optical housing. 

The Cinch-LR BA is CNC machined and type II hard anodized. They are built from the ground up for maximum functionality, performance, ruggedness, ergonomic fit, and finish.
