Johnson Level Tool 405 Brass Stair Gauge 2-pack

Product Description

The JOHNSON LEVEL TOOL 405 is a pair of brass-plated stair gauges designed to speed up layout work on stairs and rafters. Each gauge mounts flush to the blade of a framing or carpenter square using a thumbscrew, locking the square at a precise angle for repeat cuts. The 405 is sold as a two-piece set and is built for jobsite durability. Carpenters and framers rely on this style of gauge when consistent angle repetition is critical, such as when cutting multiple stair stringers or laying out common rafters to a set pitch.

The 405 is suited for residential and light commercial framing applications. It attaches to all standard framing squares and carpenter squares, making it a versatile addition to any framing layout kit. The brass-plated construction resists corrosion and wear through repeated tightening and loosening across a full project. The set is compact and lightweight at 0.16 pounds for the pair, making it easy to carry in an apron or tool bag.

Installation Notes

A licensed carpenter or framer installs these gauges by sliding each one onto the appropriate blade of the framing square and tightening the thumbscrew to lock in the desired angle. No special tools are required beyond hand-tightening. Check that the gauge is seated flush against the blade before marking or cutting to ensure angle accuracy. Do not overtighten the thumbscrew, as this may damage the square blade finish.
