The Joseph Marples Try Square is available in three different blade sizes: 6", 9" and 12". The stocks are made from Rosewood and the blade is made from tempered, blued steel. They have a machined brass face to ensure they remain accurate and to also protect against damage. The blade is secured with three diamond washers and three steel round rivets.
All the squares are tested twice for accuracy during manufacturing and once again before despatch. The squares are tested on both the inside and outside faces, and Marples' specification for the internal angle is twice as accurate as that specified in the British Standard, an accuracy better than 0.01mm/10mm blade length.
