I bought 2 of these to help carry my monopod with camera attached using a Peak Design (PD) Slide strap and PD connectors. I connect one swivel to a Leofoto QDC-36 clasp on my monopod and the other to the camera L bracket. These swivels are well made and easy to connect/disconnect in QD slots. I have used other more expensive QD swivels--these are superior and reasonably priced!
