The ReadyCap 37mm Filter and Lens Cap Holder is a unique and efficient carrying solution for lens caps and screw-in type camera filters. This system is comprised of a 58mm-diameter base, and an adapter ring for mounting 37mm-diameter caps or filters to the base, that attaches to nearly any strap, loop, or belt for conveniently carrying these lens accessories while shooting.
The base is constructed from durable ABS plastic and features metal threads to increase rigidity as well as minimize filter jamming and has a dual sided backing plate for attaching to a strap. The backing plate utilizes two screws that insert into brass threads for attachment and can be flipped to either side to accommodate both thin and thick strap sizes. The 58mm base diameter is able to accept a wide range of adapter rings for fitting other sized lens caps or filters to the holder.
