The Arca Swiss-type 1" Quick-Release Clamp with QD (quick detach) socket from Kirk is compatible with the Kirk industry standard Quick Disconnect strap system. This allows users to attach a camera to the clamp via their attached plate, & carry the camera comfortably with a compatible shoulder or sling strap. The clamp attaches to the plate with a screw-knob locking mechanism. At the top of the plate, the laser-engraved sensor lines help you to center the camera within the clamp. The compact quick release clamp is constructed from aluminum & anodized stainless steel with a black & satin silver finish.
