Champ Insert Fastener, Separable sliding connector for gluing,

Found in millions of joints, CHAMP is a universal clamping support for all kinds of materials used in the furniture industry. Both identical halves of the connector, made of plastic, are glued into a pre-cut biscuit-groove.
Once the glue has set, the workpieces can be assembled. For a permanent joint, simply glue the surfaces of the workpieces with joiner's glue. CHAMP is designed to work as a clamp on difficult mitre joints where it is almost impossible to use clamps or press supports. The press load works directly on the surface of the joint, therefore the joint will always be very exact and tight.
