Samir & Aly Set Square Pair, 30 and 60 Degrees, 20 and 28 cm

Samir & Aly Set Square Pair, 30 and 60 Degrees, 20 and 28 cm — 280 mm long.

A set square gives you angles you can trust without measuring — the 30/60 and 45 triangles cover almost every angle a technical drawing needs, used alone or in pairs against a T-square.

Slide one along the T-square blade and you get verticals; stand a second on the first and you get parallels at any angle. A bevelled edge lifts the plastic slightly off the paper so ink cannot wick underneath and blot the line.

• 30/60 and 45 cover nearly every angle in technical drawing
• Use in pairs for parallels at any angle
• A bevelled edge stops ink wicking under the plastic
