Triangle ruler AWTools AW29803 — measuring tool, weight 135 g

The AWTools AW29803 triangle ruler is a compact measuring tool designed for precise layout and drawing tasks. Made of high-quality hardened steel with a riveted aluminium handle, this triangle provides a stable reference edge for technical drawing, on-site marking and workshop layout. It features a double-sided millimetre scale, supports 90° and 45° angles and includes a hang hole for convenient storage. The listed weight is 135 g, making it easy to handle and position during work with wood, metal or construction materials.

Advantages

The hardened steel blade ensures durable straight edges and resistance to wear while the riveted aluminium handle adds rigidity and reduces flex during measuring and marking. The double-sided mm scale offers clear incremental readings on both faces for faster measurement without repositioning. Ability to set 90° and 45° angles covers common layout needs for carpentry, metalworking and technical drawing, and the hang hole simplifies storage in a busy workshop.

Suitable for

• Technical drawing and drafting
• Carpentry and woodworking layout
• Metalworking and fabrication marking
• Construction site layout and on-site measurements
• DIY and craft projects requiring accurate right angles

Key specifications

• Material: hardened steel blade with riveted aluminium handle
• Scale: double-sided millimetre scale
• Angles: fixed 90° and 45° positions
• Weight: 135 g
• Storage: hang hole for wall or pegboard mounting

How to use

Place the triangle ruler against the workpiece edge or drawing board so the steel blade sits flush. Use the millimetre scale to measure distances directly along the blade and mark points with a pencil, scribe or awl. To mark right angles, align the handle or blade against the reference edge and scribe along the adjacent blade to create a 90° or 45° line. Apply steady, even pressure to keep the ruler from shifting; the aluminium handle and rivet provide added stability during marking.

Usage recommendations

Store the triangle on a pegboard or hang rail using the hang hole to prevent edge damage. Clean the steel blade after use and protect it from moisture to reduce corrosion risk. For the most accurate results, use a sharp scribe or fine pencil and ensure the reference edge is free of debris before marking.
