Try Square 12in 300mm Aluminium Dual Metric & SAE Markings

A 12in / 300mm try square for marking out and checking clean 90° lines on timber, sheet material and finished work. This aluminium try square gives a straightforward way to set out right angles accurately, whether you are cutting, fitting or checking corners before fixing parts in place.

Used across carpentry, joinery, workshop jobs and home DIY, it suits both regular trade use and general maintenance work around the house. When marking shelves, frames, boards or trim, an aluminium square like this helps keep cuts and joints true. It is also useful for checking corners during assembly, verifying finished work, or laying out basic lines before sawing, drilling or fastening.

The 12in / 300mm size makes it a practical choice for general measuring and layout work without being awkward to handle or store with other hand tools. Made from high grade aluminium, it has a solid feel for repeated use in the workshop, on site or in the garage. Dual metric and SAE markings make it easier to work in the measurement system already being used on the job, which can help avoid switching between tools. For anyone carrying out regular joinery, fitting or repair tasks, it is the sort of square that earns its place quickly because it covers common marking and checking jobs.
