Sourcing Locksmith's Angle with Foot YT-70765 300 x 200 mm measuring square

The Sourcing Locksmith's Angle with Foot YT-70765 300 x 200 mm measuring square is a right-angle layout tool designed for metalworking and woodworking tasks. It combines a 300 x 200 mm square blade with a rigid foot that stabilizes the tool on flat or slightly curved surfaces, allowing accurate marking, checking of 90° angles, and alignment during assembly and fabrication work.

Advantages

This measuring square provides stable positioning thanks to its fixed foot, reducing movement when scribing or transferring lines. The substantial 300 x 200 mm size offers a clear reference for larger parts while still being manageable for bench and workshop use. The simple, durable construction makes it suitable for repeated contact with workpieces without complex adjustments.

Suitable for

• Layout and marking of right angles in metal fabrication
• Checking squareness of machined or cut parts
• Carpentry tasks requiring consistent 90° references
• Assembly and fitting where stable positioning is needed

When it may not be suitable

This locksmith's angle is intended for general workshop marking and squareness checks and does not replace precision laboratory squares for metrology-grade measurements. Very small or highly detailed layout work may be better served by smaller precision squares or combination squares with fine adjustment features.

Key specifications

• Blade dimensions: 300 x 200 mm (approximate working size)
• Type: Right-angle measuring square with rigid foot
• Primary materials: metal blade with rigid support foot (durable construction for workshop use)
• Main use: layout, marking, and squareness checking

How to use

Place the rigid foot flat against the reference edge of the workpiece so the blade sits squarely across the surface. Hold the foot firmly to prevent slipping and scribe or mark along the blade edge to transfer a 90° line. For checking squareness, align one blade with a known reference edge and inspect the other blade against the part's edge; any gap or light indicates deviation. Clean contact surfaces before use to maintain consistent seating.

What to consider before purchase

• Required accuracy level: suitable for workshop layout but not for laboratory-grade metrology
• Size compatibility: 300 x 200 mm blade best for medium to large parts
• Material and durability for your shop environment
• Whether a fixed-foot square fits your typical clamping and positioning needs

Usage recommendations

For reliable results, keep the foot and blade clean, clamp the workpiece when possible, and verify the square periodically against a known reference. Use the tool for marking and rough squareness checks and pair it with finer measuring instruments when higher precision is required.
