This range of large marking/measuring tools is primarily for use with sheet materials or large projects.

The 18" & 24" try squares have rosewood stocks, blued spring steel blades, and are secured by five brass diamond washers with steel rivets, and a 3mm thick machined brass face plate. As these squares may be used on sheet material, at the toe of the stock is a small retractable blade, which, when out, sits on the edge of the sheet and stabilises the square.

The panel gauge allows lines to be gauged past the centre of a 56" wide panel. The stem is 30" long and the head 9" wide with a brass wear strip fitted inside a rebate which rests on the edge of the panel to be gauged.

The adjustable angle square has one stock set at 90°,  the other may be set at any angle and locked in place bt a large brass, knurled thumbscrew. Both have brass wear strips, the blade length is 24".
