The TM-AR086 TOUGH MASTER Multi Angle Ruler is a universal template tool for carpenters, bricklayers, woodworkers, tilers, and other trades professionals. It is made from high-quality 5mm aluminium alloy, a material that is corrosion-resistant and built to last, especially when compared to plastic which is likely to suffer from rust and wear-and-tear over time. The multi angle measuring ruler has 6 folding slides to easily create and measure those tough, tricky areas, improving your work efficiency in the process; while the metal knobs adjust to make your shape as accurate as possible. Moreover, there are laser-engraved lines that are clear to read, displaying both centimetres and inches, so you can choose to measure in either (or both) - whatever your preference. The locator on the universal foldable ruler is equipped with 6 shape-drilling holes, with 25/40/45/55mm circular holes and 63/73mm square. The shape duplicator is made from ABS plastic for increased durability and a lighter weight, making it easier to measure without hand strain. Store the adjustable multi angle ruler comfortably in a tool bag, thanks to its compact size of 19 x 16 x 2cm. This measuring tool is highly recommended for its user-friendly design; just place it onto your work area, adjust the 6 knobs and slide the rulers to make your ideal shape, remembering to tighten the screws, too.
