The Saker folding multifunctional level is 28 inches long. Imagine, this level can fold into a compact rectangular unit for storage, and when needed, unfold into a regular straight level. No storage or transportation problems at all! It's easy to put in any toolbox and take with you to the site. The level features 4 obvious blue acrylic flasks. The measurement accuracy is 0.5 mm per meter - an excellent figure for professional work both indoors and outdoors. The body is made of oxide-coated aluminum profile - rust-free and scratch-resistant, while ABS plastic joints and TPR end pads serve as double protection against accidental drops. You can fold it at any angle to get around obstacles or measure multiple angles at once. This is especially useful when working with pipes, ladders, corners and complex structures.
