- Material and durability: Made from aluminium alloy, these tall stair gauges are tough, reliable, and resistant to deformation. Precision metal fabrication gives the gauge tool a refined, durable build. - Thoughtful design: Rafter layout keeps your framing square upright and stabilizes the angle, enabling specific and accurate measurements without hassle. - Strong performance: The height supports solid and accurate positioning and measurement. With dual slots and cylinder barrels, the stair gauges accommodate a wider range of projects. - Strong compatibility: The slot is 1/4in tall and fits onto anything up to 25in thick. - Convenient to carry: Lightweight design reduces burden and allows you to move and place the gauge as needed, providing greater ease and flexibility. - Use scenarios: - Framing stairs: Use with a framing square to maintain consistent rise and run on stair stringers. - Roof and rafters: Align and set angles for rafters during roof framing. - General carpentry: Achieve precise height alignment and measurements on multiple pieces such as cabinets, furniture, or trim work.
