The Really Right Stuff VYCE Rail Vr-76 is designed to securely hold the RRS VYCE to any RRS quick-release clamp. The VR-76 is machined from a solid block of aircraft grade aluminum. The VR-76 is an all-purpose QR plate, and is specifically designed to enhance the mount time of the VYCE to RRS ball heads and leveling bases. The QR mounting feature allows existing equipment, typically without pre-existing mounting plates, to be securely mounted to tripods and ball heads while maintaining consistent performance with your RRS support system.FeaturesAll corners and edges are rounded for better feel and ergonomicsTumbled, satin finishCNC machined 6061-T6Hard-Anodized; Type-2 BlackTwo 3/8"-16 threaded accessory mounting socket1/4"-20 threaded accessory mounting socket
