Availability: Out of stock

Robert Sorby Logo
  • A fine sealed walnut 18 inch (450mm) Joseph Marples try square.
  • This square incorporates 3mm thick brass strips on inside face to ensure accuracy.
  • Each of these Marples squares have been tested for accuracy two times during the manufacturing process and again just before leaving the factory.
  • 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 tempered spring steel blade is chemically blued and secured to the stock with decorative brass diamond washers and steel rivets.

The accuracy of the try square is well within that required by the British Standard: BS3322.

These squares have been tested on both the inside and outside faces, with the internal angle being twice as accurate as the British Standard, an accuracy better than 0.01mm/10mm blade length.

This nicely engineered tool is modelled on old Marples try square designs from over 70 years ago.

Model: 18" (450mm)Try Square
Tool Manufacturer: Joseph Marples (Sheffield, England)

Note: the aesthetics of the blued steel can vary between each square
