Rotary lasers and line lasers are used for commercial and residential building applications. Rotary lasers are ideal for checking that foundations are level, shooting control lines so that windows and doors line up, installing wainscoting, setting kitchen cabinets, laying walls, installing decks, balustrades, and siding - all with only one person. Rotary lasers are also used to calculate plumb, level and square for walls, ceilings and roofs. Accessories for rotary and line lasers include carrying pouches, storage cases, receivers, wall brackets and target plates.
