This router jig helps to cut the rebate for all Type 1 Button-fix, and to position the fixing pilot holes for both rebated and surface-mounted installations. The jig requires a router fitted with a 12mm cutter and 16mm guide bush. The jig features countersunk holes for screwing directly onto the panel to position the Button Fix wherever it is required. The pilot holes require a 3mm drill bit. Size 250 x 180 x 8mm.
