When it comes to putting a box or carcass together, this is a truly useful accessory. Used in conjunction with a multifunction table, the Assembly Square is a very effective third or even fourth hand when trying to join the corners of a cabinet carcass or frame.

It is an L-shaped section of CNC machined, HDF Valchromat with 360mm long legs. The legs are exactly at 90° and feature a group of 3 x 20mm dog holes. These holes align diagonally with the multifunction table dog holes. Any 20mm guide dog will work but the 12mm UJK Guide Pups are the ideal for this purpose. Once in place the Assembly Square forms a reference for a fast, spot-on and accurate way to set up a guide rail for 45° mitre cuts.

The square really comes into its own as an assembly aid for box, frame or carcass construction. Having cut all the pieces with the utmost precision, the Assembly Square ensures the parts go together at right angles. The arms have cutouts for clamps and holes for spigot clamps with which to hold two pieces while gluing, screwing, fixing etc.

Positioned in place on a multifunction tabletop with guide pups, the addition of a couple of UJK cam clamps can lock both parts against the square while fixing. You can use a second Assembly Square to secure the top.

Valchromat is certified by the Pan European Forest Council (PEFC).
