Peak Design Anchor Mount PL-AN-1 Includes hex wrench. This was originally attached to a strap, but I never used it and have kept it in storage. [Product Overview] *Quoted from the website A mount for attaching many straps, including Peak Design straps, to the bottom of a camera. This thin, unobtrusive Anchor Mount differs from conventional tripod plates and, in many cases, does not interfere with the battery door or vari-angle LCD screen. Furthermore, when one side of the strap is connected to the bottom using the Anchor Mount, the lens faces downwards, increasing stability, especially when carrying long lenses.
