Joiners cramp for securing edge moulding on panel corner - uses frame with bolt and sleeve screw clamp on one end and perpendicular anchor finger on other

摘要

The joiner's cramp is used to secure edge mouldings on the corner of a composite panel, comprising a frame with a clamp and a perpendicular anchorage finger on opposite ends. The clamp comprises a bolt screwing into an internally threaded sleeve, one end of the bolt having a driving handle whilst the other locates a pad transmitting pressure to the work. The clamp and finger may be mounted on the same side of the frame which may comprise a straight length of steel bar. Alternatively, the frame may have a 'U' shape with the clamp fixed to one leg and the finger constituting an extension of the other leg. The finger may have a round cross section and engage a panel hole whilst the clamp pushes the moulding onto the panel edge.
