The Chop Lock is an innovative solution for attaching a chest-mount rebreather without needing to remove or unweave your harness shoulder straps. With only three inches of open space on the harness, the Chop Lock can be installed quickly and hassle-free. It’s ideal for dialing in the position of your rebreather with ease. Designed for chest-mount rebreathers and other lightweight accessories, the Chop Lock is not intended for stage cylinders. Sold in pairs.
