Aluminium 45° Folding Triangle Tool

Approximately 59 cm × 59 cm × 84 cm in size, this triangle ruler is made entirely from corrosion-resistant aluminium alloy. Its folding mechanism uses metal rivets — not plastic pins or friction hinges — to secure the two legs in open or closed positions. Permanent ink-printed scales on both sides offer 1 mm metric and inch-based measurements, fully visible without glare or fading. Designed for daily use across disciplines, it supports accurate line extension, perpendicular checking, 45° layout, and repetitive marking — whether laying out kitchen carcasses, drafting engineering sketches, or adjusting shelving brackets in home offices.
