The 300mm Faithfull Prestige Adjustable Quick Roofing Square is the larger variant, ideal for extended reach and marking out bigger building projects. This size is particularly well-suited to working with longer rafters and larger-scale roofing applications where greater measurement range is essential. Manufactured from aluminium using CNC machines, this square features a black anodised finish for enhanced corrosion protection and laser-etched scales for outstanding measurement accuracy. It combines the functions of a combination, try and framing square, plus serves as a saw guide for 45° and 90° cuts and a protractor for measuring angles and pitches. The adjustable protractor arm locks securely with a brass screw for repetitive cuts.
