Stanley 46-053 Aluminium Adjustable Quick Square with Arm

The Stanley 46-053 is an adjustable quick square with an arm, made from heavy-duty aluminium for long life. Its black body carries yellow graduations that Stanley says give maximum readability in various light conditions. The square is marked with common, jack and hip, and valley scales, and Stanley classes it as a roofing and rafter square. An adjustable arm helps with precise settings, and the multipurpose design doubles as a saw guide, a bevel or a protractor. A useful layout tool for carpenters and roofers.
