CD40 Arca-Swiss Compatible Back-to-Back QR Clamps

For sale are Arca-Swiss compatible clamps, back-to-back mounted at either 90 or 180 degrees as seen in pictures.This action includes two 40mm wide clamps.Hard coated black anodized surfaceNickel-chrome plated insert, this ensures that threads will remain in good condition almost indefinitely, as opposed to all other designs that have threads cut directly in the aluminum body of the clamp, rending it useless once the threads wear out in the aluminum.These can be used for paralax offset and other slide the rail applications, or separately.  These are precision machined instruments, and even when screw is removed from clamps they will stick together just on the pins, because its really a tight fit, to pull them apart you have to pull very evenly, as there is almost no play, also when mounting back please don't forget to use the big screw to secure both clamps together.Fits Really Right Stuff, Arca-Swiss, Markins, Kirk, Jobu Design or any other standard Arca Swiss plate.DESIGNED & MADE
