Customer Reviews (4.8 / 5 · 5 reviews)

Victoria ★★★★★

The lock bolt on this square feels solid and holds the blade tight without any wobble, which is exactly what I needed for precise layout work. The spirit level is a nice bonus for quick checks, and the whole tool has a nice heft to it.

Owen Z. ★★★★★

The engraved markings on the blade are crisp and easy to read, and the scriber is a handy bonus. This is the most precise square I've owned.

Steven ★★★★★

The cast iron head feels rock solid in hand, and that reversible lock bolt makes switching between inside and outside measurements effortless. The spirit level came in handy more than I expected, and the photoengraved blade is still crisp after a week of shop use.
