Aluminum rulers/ruler boards are suitable for measuring and leveling work where perfectly straight or even surfaces are required. They are particularly suitable for leveling floor screeds, but they can also be used for checking the levels of frame joists and as long sawing guides when sawing building boards.

Aluminum rulers are available in several different sizes and with beveled edges. The desired length depends on the intended use. Long ruler boards can be used to measure the height differences of several different battens and level them, and to level large amounts of floor screed at a time.

All the ruler boards are made of durable and lightweight aluminum, and they have a built-in support frame that prevents the ruler from warping. The rulers also have removable end caps, which allows them to be shortened by sawing if necessary.
