A double vise (1,2) holder takes wall and uncut fitter piece so the holder legs (4,5) and base (3) stand at right angles. The base (10) of the vise jaw (1) also forms the non-screw side leg (10) of the second vise jaw (2). The jaw (1) side leg (5) carrying the screw system (6-8) lines up with the second vise jaw base (9). The parallel edged mark-out template has an edge interval equal to the interval between the inside of the free leg (4) of vise (1) and the inside of vise (2) base (9), measured at right angles. The holder is a casting and vise screws (8) run in bushings plugged into the vise (1,2) openings.
