12" Aluminium Carpenter's Square with Spirit Level — 300mm Metric & Imperial Two-Sided Graduated Blade

Accurate squaring is the foundation of good carpentry. Whether you're framing, setting out, or checking your work at the end of a job, this 300mm aluminium carpenter's square gives you a reliable reference point every single time. It's straightforward to use, built from decent materials, and offers more functionality than a basic try square at a price that makes it an easy addition to any toolkit.

The blade is made from aluminium and measures 300mm (12 inches) in length. Both sides are graduated in metric and imperial, which makes it easy to use whatever unit of measurement your job calls for without having to mentally convert figures as you go. The markings are clean and well-defined, sitting flush against a smooth blade surface that rests flat against your timber or workpiece without rocking.

The stock — the shorter fixed arm that butts up against the edge of your material — is solid and sits at a true 90° to the blade. The resettable combination feature means you can adjust and re-lock the position to suit different marking depths or shoulder widths, giving you more flexibility than a fixed square allows. The built-in horizontal spirit level vial adds another dimension of usefulness, letting you confirm level as well as square without reaching for another tool.

Light enough to carry around a site all day, accurate enough to rely on for fine joinery work, and priced so that keeping a spare in the van makes sense.
