Aluminum Alloy Stair Gauge Clamp – Framing & Rafter Jig
Aluminum Alloy Stair Gauge Clamp – Framing & Rafter Jig
Aluminum Alloy Stair Gauge Clamp with Thumb Screw – Framing & Rafter Woodworking Jig
Take the guesswork out of stair layouts and rafter cuts with this precision-crafted Aluminum Alloy Square Auxiliary Clamp Stair Gauge. Designed for carpenters, framers, and woodworking enthusiasts, this compact clip attaches securely to your framing square, letting you mark and repeat angles with consistent accuracy every single time.
Key Features
- Premium Aluminum-Copper Alloy Construction: Built from a robust aluminum-copper alloy, this stair gauge delivers excellent strength and corrosion resistance for long-lasting, reliable performance job site after job site.
- Hexagonal Body Design: Unlike round-profile gauges, the hexagonal shape grips edges more securely and keeps the framing square perfectly perpendicular to your material — resulting in highly stable, precise clamping.
- Versatile Woodworking Use: Ideal for marking repeating angles on framing squares, guiding saw cuts on rafter squares, setting stair stringers, and a wide range of woodworking layout tasks.
- Consistent Stair Layouts Every Time: Lock in your rise and run measurements once and reproduce them perfectly across every stair step, saving time and reducing measurement errors.
- Thumb Screw Locking Mechanism: The easy-turn thumb screw provides fast, tool-free adjustment and a rock-solid lock on your framing square blade.
- Portable Anti-Loss Design: Compact and lightweight, this woodworking auxiliary clip is easy to store in a tool belt or toolbox and features an anti-loss design to keep it secure during transport.

Frequently Asked Questions
Q: What is a stair gauge clamp used for in woodworking?
A: A stair gauge clamp attaches to a framing square and acts as a stop or reference point, allowing you to quickly and repeatedly mark the same rise and run measurements for stair stringers, rafter cuts, and other repetitive angle layouts. This aluminum alloy stair gauge ensures consistent, accurate results every time you reposition your square.
Q: Will this stair gauge fit any standard framing square?
A: Yes. The thumb screw locking mechanism allows the clamp to adjust and fit securely onto the flat blade or tongue of most standard framing squares and rafter squares. Always check that the gauge is firmly tightened before marking.
Q: Why is a hexagonal design better than a round stair gauge?
A: The hexagonal body provides more contact area along the edge of the framing square blade, which prevents rotation and wobble during use. This means more stable clamping and more precise angle markings compared to traditional round-profile gauges.
Q: Is the aluminum alloy construction durable enough for job site use?
A: Absolutely. The aluminum-copper alloy used in this stair gauge offers an excellent combination of lightweight portability and high strength, plus natural corrosion resistance — making it well-suited for both workshop and on-site framing applications.
