These hand straps feature a dual channel for the 3/8" webbing accross the back of the hand for maximum distribution of camera weight. The webbing will attach to the standard lugs found on most cameras. For cameras with a verticle grips, you should find a bottom lug already on the camera. For cameras without a verticle grip, you will most likely need to purchase a bottom plate. We will be offering these shortly, however, do not yet have any available. Until then, we recomend a plate from these guys.
