Geko Rafter Square 12” 300mm

Made from high-quality aluminum, this carpenter’s square ensures measurement accuracy and convenience during carpentry, construction, and finishing tasks.

With a thickness of 4 mm and a rigid, wide base, the square maintains stability when applied to the material, guaranteeing precise guidance for a saw, pencil, or marking tool.The surface is anodized, which increases resistance to corrosion, scratches, and external factors – even when working in harsh workshop or construction site conditions.

Product Features:

• Material: high-quality aluminum – lightweight yet resistant to deformation during measuring or marking.
• Thickness: 4 mm – rigidity and durability that allow for accurate application and tool guidance.
• Dimensions: 300 × 300 × 430 mm – a universal size suitable for most carpentry and construction tasks.
• Colour: vivid blue – enhances visibility of the square against both light and dark materials.
• Engraved scales – wear-resistant, they won’t fade even after years of use.
• Coating – protects against rust and abrasion in everyday working conditions.
• Double-sided markings – make readings easier regardless of the square’s position.
• Wide base on one arm – stable support that allows easy and secure alignment with material edges.

Precision markings and measurement guides:

The square features a set of precise scales and conversion charts to simplify calculations without needing additional measuring tools:

• Angle scale – range from 0° to 90° with clearly marked degrees.
• Centimeter and millimeter scale – on the lower and upper edges for quick linear measurements.

Conversion tables:

• Converts inches to feet – quick reference for inch-to-foot conversion.
• Common rafter conversion (inch rise / foot = degrees) – conversion from “inch rise per foot” to pitch degrees – useful for roof framing.
• HIP-VAL / COMMON / TOP / CUTS markings – assist in laying out rafters and carpentry cuts.
