Promaster Dovetail QR Clamp Kit

The ProMaster Dovetail QR Clamp Kit is a great way of adding an Arca-type quick release to a tripod, head, grip item, or other piece of equipment. It uses a 3/8"-16 threaded port and includes a 1/4"- 20 adapter. The clamp body also has three strap slots, so it can be used as a quick release system for a shoulder strap. 

This kit includes a ProMaster 50mm Quick Release Plate (1816) which incorporate two removable safety bolts to prevent it from accidentally sliding out of the clamp.
