The Toyo-View 180-753 40mm Tripod Mounting Block is the compact mounting block supplied with the VX125R camera, which has a 125mm fixed monorail (instead of a 125-250mm telescoping monorail as supplied upon the VX125). This tripod mounting block is not intended for use with any other Toyo-View camera; it is available here as a replacement for a lost or damaged unit.
