A woodworking square designed for accurate, repeatable markings and tough site use. Using the Senbaler Triangle Ruler helps DIYers and tradespeople mark quickly with confidence. Is it precise and robust enough for regular carpentry and roofing work?
⚡ At a Glance
- • Measuring Accuracy: Laser-printed metric and imperial scales, clear and resistant to wear
- • Best for: Carpenters, roofers and DIY enthusiasts needing repeatable angle marking
- • Not ideal for: Tasks that require digital readouts or electronic measurement tools
Aluminium alloy construction with a smooth, even coating and laser marking. One 90° angle and two 45° angles, plus a rafter conversion table on the back.
Precise Marking - with laser-printed metric and imperial scale
Laser marking technology prints the scale clearly onto the aluminium surface, producing high-precision graduations that resist wear. The scale supports both metric and imperial measurements for flexible use.
Highly repeatable scribing and layout lines, so cuts and joints align more reliably. Fewer measurement re-checks and less material waste.
Site-Proof Durability - with aluminium alloy construction and protective coating
High-quality aluminium alloy offers good hardness and moderate toughness, while an even coating resists rust and corrosion. The construction resists deformation and remains serviceable after drops.
A long-lasting tool that copes with workshop knocks and damp conditions. Keeps its shape and scale legibility over time.
Faster Rafter Layouts - with a right-angle base and conversion table
A horizontal base includes one 90° and two 45° angles for quick squaring and angle transfers, while a conversion table on the reverse lists common rafter values. The right-angle base sits flat for stable marking.
Speeds up roofing and rafter marking by reducing calculation steps and measurement fiddling. Easier alignment for straightforward straight cuts and angled rafters.
