TOPMAN 300 x 160mm Carpenter's Square JTM-1884-008

With a fine tolerance, this small lightweight square should be in all kits, on all shelves or every workshop drawer. With the ruler measuring 30cm x 15cm, it is the right size for smaller jobs, and at 1.1mm thick, it is strong enough, small enough and light enough to be constantly sought after. Tolerance 0.1 mm or less per 100mm square.
