PTI Adjustable Roofing Square 12 Inch, 12" Aluminum Alloy Rafter Square, Metric & Imperial Carpenter Square Set, Precision Speed Square Carpenter Pencils Woodworking Tool Set

*DESIGN* - This multi-functional roofing square set is the perfect tool to get straight edges and lines with the lockable and adjustable protractor arm. The cuts which line up closely with the measures on the square allow you to scribe parallel lines more accurately. The brass screw of the adjustable slider is bigger, so easier to tighten/loosen. *STRONG*: We use Heavy duty aluminium so it's sturdy and solid enough when doing multiple cuts. And the black coating finish offers great corrosion protection. *CLEAR & CONCISE* - The laser engraved marks on both sides are resistant to wear and convenient to read when working. *MEASUREMENT* - Metric and imperial graduations, Manufacturer: Professional Tool Industries
