Geometric 45° Triangle Ruler Linex S2622, SAN Transparent, 22.5 cm side, 2 mm thickness

Linex S2622 is a 45° geometric triangle ruler made from transparent Styrene Acrylonitrile (SAN) with a 22.5 cm side and 2 mm thickness. The clear material offers good visibility of drawings and measurements while the flat profile provides stable handling for drawing, measuring angles and guiding cutting tools. The tool combines a ruler, set square and protractor functions in one compact geometry instrument suitable for classroom and technical use.

Advantages

The Linex S2622 features a glass-clear SAN body that gives clear sight of the work surface and printed diagrams. The 2 mm thickness provides rigidity during use and reduces flexing when drawing long lines. An anti-slip rubber strip on the back improves grip on paper or drawing boards, helping to keep the triangle in place during precise lines or measurements. The integrated protractor marking and a magnifying area over zero aid accurate angle reading, while the straight and beveled edges and tracing edge increase versatility for different drawing and measuring tasks.

Suitable for

• Students studying geometry, technical drawing or design
• Architects and designers making sketches and scaled drawings
• Teachers and classrooms for demonstrations and practice
• Hobbyists needing precise angle measurement and straight edges

When it may not be suitable

This 45° triangle is optimized for general drawing and angle work but is not a heavy-duty cutting guide for industrial applications; prolonged contact with sharp blades can wear the edges. It also does not include graduated metric scales beyond the side length markings, so users who require specialized scales or extremely fine fractional graduations may prefer a dedicated engineering ruler.

Key specifications

• Shape and angle: 45° geometric triangle
• Material: transparent Styrene Acrylonitrile (SAN)
• Side length: 22.5 cm
• Material thickness: 2 mm
• Anti-slip feature: rubber strip on the back
• Functions: ruler, set square, protractor with magnifying area
• Edges: straight, beveled and tracing edge

How to use

Place the Linex S2622 on the paper or drawing surface with the anti-slip strip against the sheet to secure it. Use the straight or beveled edge for drawing lines and the hypotenuse or side edges for measuring lengths up to 22.5 cm. Position the protractor markings at the vertex to measure or set angles; use the magnifying area to align the zero precisely. For cutting tasks, hold the triangle firmly and guide the cutter along the outside edge, taking care to avoid heavy repeated blade contact to preserve the edge.

What to consider before purchase

• Confirm 22.5 cm side length meets your measurement needs
• Consider 2 mm thickness for the required rigidity and portability
• Transparent SAN material for visibility; check compatibility with drawing surfaces
• Anti-slip rubber strip useful for paper and drawing boards but may not adhere to highly textured surfaces

Usage recommendations

For best results, store the triangle flat to avoid warping, clean with a soft cloth to remove pencil residue, and avoid prolonged use as a cutting fence against sharp blades to preserve the straight edges and markings.
