Angle with Foot Sourcing YT-70766 400×250 mm — locksmith's measuring square

Sourcing YT-70766 400×250 mm is a locksmith's measuring square with an integrated foot support, designed for precise layout and verification of right angles on metalwork and woodworking. The square combines a rigid blade and a stable foot to hold the tool firmly against workpieces, allowing accurate marking, squaring and transfer of dimensions in fabrication, welding and workshop tasks.

Advantages

The solid construction ensures minimal flex during positioning, while the foot support provides firm contact with flat surfaces for repeatable measurements. Its 400×250 mm arm proportions offer extended reach for larger components without sacrificing control at the blade edge. The finished edges allow clear marking and consistent alignment when checking or setting out 90° angles.

Suitable for

• Layout and marking of metal sheets, plates and profiles
• Checking squareness of welded assemblies and fabricated parts
• Carpentry tasks requiring accurate right-angle transfer and layout
• Workshop measuring where a stable footed square speeds repetitive checks

Key specifications

• Arm lengths: 400 mm and 250 mm
• Tool type: footed squares for right-angle layout
• Construction: rigid blade with foot support for stable positioning
• Primary use: marking, squaring and measurement transfer for metalwork and woodworking

How to use

Place the foot of the square flat against the reference surface so the blade forms a true 90° with the workpiece. Hold the tool firmly against the edge to prevent movement, then scribe or mark along the blade edge for an accurate layout line. For checking squareness, align one arm to a reference edge and verify that the opposite edge contacts the other arm without gaps; adjust the component or fixture as required before fixing or welding.

Usage recommendations

Use on clean, flat reference surfaces and keep the blade edge free of burrs or nicks for best accuracy. Store the square in a dry place to avoid corrosion and inspect the foot and blade before precision work. For repeated production checks, combine the square with a stable clamping setup to minimize manual variation.
