## Long description

Proline triangle 21350 is a single-piece hand tool for marking, measuring and checking angles in woodworking, metalworking and general DIY. Compact and lightweight, it combines a rigid triangular structure with dual metric and inch scales on both sides to support layout, verification of square and angled joints, and quick on-site measurements. Supplied as one piece, the tool is intended to fit into workshop toolsets, toolboxes and mobile repair kits.
Advantages
The triangular form provides stable reference faces and improved durability during repeated use. Dual-sided scales in metric and imperial units reduce the need for conversions and speed up measuring operations. Its compact size and single-piece construction make it easy to carry, store and use in confined spaces while maintaining sufficient rigidity for accurate marking and checking.
Suitable for
 Marking and checking right angles and bevels in woodworking
 Measuring small components and layouts in metalworking
 General DIY tasks, on-site repairs and assembly work
 Carpentry, joinery and furniture fitting tasks
Key specifications
 Form: rigid triangular structure for stable reference
 Scales: metric and inch scales, printed on both sides
 Material and finish: single-piece hand tool with durable construction
 Supply: sold as one piece for individual use or as part of a toolkit
 Size: compact, suitable for confined workspaces and toolbox storage
How to use
Place the triangle against the workpiece so that one of its legs bears firmly on the reference edge. Read the required value from the appropriate scale side (metric or inch) and mark the workpiece with a pencil or scribing tool along the reference edge. Use the flat faces for checking squareness by aligning the tool with two surfaces; any gap or light between the tool and the surface indicates deviation. For angle layout, rotate the triangle to the required orientation and transfer the line to the workpiece, taking measurements from the printed scales as needed.
Usage recommendations
Keep the scales clean and free of debris to ensure accurate readings. Store the tool in a toolbox or protective sleeve to prevent damage to the printed scales. Use light, consistent pressure when placing the triangle against a reference edge to avoid marking or marring finished surfaces.
