Aluminum Alloy Triangle Gauge Angle Ruler 7" / 12"

Accurate Angle Marking for Professional Woodworking

Achieve clean, repeatable cuts and layouts with this Aluminum Alloy Triangle Gauge, designed for precise measuring and marking in woodworking, carpentry, construction and layout work. Built for consistent accuracy, it combines angle marking, straight-edge measuring and quick referencing of common cuts in one compact tool, supporting both metric and imperial workflows.

Manufactured from robust aluminum alloy, this triangle gauge offers high hardness and strong resistance to wear and surface oxidation, helping it maintain accuracy over long-term use in the workshop or on site. The clear, finely etched scale markings are easy to read and resist fading, supporting both metric and imperial measurements for flexible use across different project standards. Available in two practical formats, the 7-inch version (approx. 260 × 185 × 185 mm) is ideal for portable, on-site work and smaller stock, while the 12-inch version (approx. 430 × 305 × 305 mm) offers extended reach for framing, panel work and larger assemblies. Its triangular form provides stable reference edges for marking and checking angles, laying out rafter cuts, squaring boards and setting tool angles. Supplied as a single triangular ruler, it is suitable for woodworking, construction layout and basic surveying tasks where reliable angle and length reference is required.

Why It's a Smart Choice

• Supports both metric and imperial scales for easy use across different project standards.
• Durable aluminum alloy body with high hardness and anti-oxidation properties for long service life.
• Triangular design provides stable, accurate angle reference for faster, more consistent marking and measuring.

FAQ

Q: Is this triangle gauge suitable for professional carpentry work?
A: Yes. Its rigid aluminum alloy construction, clear dual-scale markings and stable triangular design make it suitable for both professional carpenters and serious DIY users.

Q: Can I use it for both metric and imperial measurements?
A: Yes. The ruler includes both metric and imperial scales, allowing you to work comfortably with plans and materials specified in either system.

Q: Which size should I choose, 7" or 12"?
A: The 7" version is convenient for smaller pieces, trim work and portable tool bags. The 12" version is better for framing, sheet goods and larger layout tasks where longer reference edges are helpful.

Q: Is the surface resistant to rust and wear?
A: The aluminum alloy body with anti-oxidation treatment helps protect the surface, maintaining legible markings and a smooth reference edge over time under normal workshop or site conditions.
