## Long description

Proline 21335 — 1 piece measuring triangle for drawing and layout is a single-piece triangle measuring tool designed for precise drawing, layout and angle marking. The tool offers a rigid structure and a stable straight edge suitable for use in workshops, construction sites, classrooms and home projects. With both metric and inch scales printed on two sides, the measuring triangle supports work that requires quick measurement, alignment and transfer of angles.
Advantages
The measuring triangle features a one-piece rigid construction that resists twisting and keeps edges straight during use. Dual-sided scale markings in metric and imperial units allow flexible use with different work standards and drawings. The lightweight form factor combined with a stable profile makes the instrument easy to handle for marking, sketching and checking squareness. Surface markings are visible and placed to support common layout operations without obstructing the straight edge.
Suitable for
Technical drawing and drafting in workshops and studios
Carpentry layout and on-site angle marking
Educational use in schools and training courses
General measurement and alignment tasks in DIY projects
Key specifications
Construction: single-piece rigid triangle
Scale types: metric and inch scales on both sides
Functionality: straight edge for drawing, angle marking and layout
Typical applications: drawing, carpentry, construction, education
How to use
Place the triangle on the work surface with the straight edge aligned to the line or edge you need to mark. Read measurements from the appropriate scale side—metric or inch—depending on your drawing or material. Use the triangle edge as a guide for pencil, scribing tool or cutting guide to draw straight lines and transfer angles. For layout tasks, hold the triangle firmly against the reference edge to maintain squareness while marking multiple points.
Usage recommendations
Store the measuring triangle flat to prevent warping and protect the scale markings from abrasion. Clean the edge regularly and avoid using excessive force as this may damage the straightness of the edge. When switching between metric and inch measurements, verify alignment against a trusted reference to maintain accuracy.
