The clip is designed for a 60mm wide shoulder. I've added a knot trap one side for a camera retaining system and a larks foot hole on the other side. It is based on a round puck that has similar dimensions to an Arca-Swiss mount. There is a retaining clip built into the back plate which means you will need to build with support from the build plate, have mine set to 75 degrees to limit the amount of support. I designed this for use with My Sony A6000 and RX100, both light cameras, so bear that in mind if you have a monster outfit. The Larks foot hole and knot trap are designed for 2mm dyneema cord. If you tie a figure of eight know at the end of your tether with 30mm of rope after the knot, then it is easy to pull the knot into the trap and then easy to pull it back out with the 30mm end.
