Hanging or mounting mechanism comprises a support tube on which a plate or board is mounted. The mechanism further comprises an upper metal clamping roll (3) which when clamped is on the rear side of a support tube (6) and on the upper side of a working plate (1). It is adjusted using two adjustment screws that link it to a lower clamping roll. The plate (1) is supported by lever action and friction alone, with the lever action created by the center of gravity of the plate and any object placed on it. |
