The Q=Mount X is a unique tripod quick release which allows a Novoflex QPL or Arca-pattern quick release plate to be clamped in one of two directions. The corner clamp mechanism allows the plate to be quickly removed and reset at 90° to the previous position. It can be mounted on any head with a 1/4" screw (or using the supplied male screw, into a head with a socket). Dimensions: 64 x 64 x 12mm. Weight: 180g n.b. not supplied with plate
