UJK Squares | One family, absolute accuracy

Introducing the UJK Squares family, together they have every angle covered. Designed, developed, and manufactured in Britain, UJK Squares are precision-led, engineering-accurate squares for woodworkers who demand the best.

Why does woodwork need that level of precision?

Because fine furniture, kitchen cabinets, or picture frames all demand professional angles and cuts for a flawless finish.

Who's in the UJK Squares' family?

Let's break it down to what each of the UJK squares brings to the table:

At the head of the family, we have the UJK Professional Woodworker’s Marking Square. With versions in 150mm, 250mm and a colossal 350mm! The accuracy of these squares conforms to DIN 875 Grade 00, with a calibration certificate included - that's engineering accuracy, unmatched by any other woodworker's square!

What else?

  • Multi-function design – marks 90°, 45°, or any angle 10°-90°, plus centre lines and radii
  • Practical details – tapered pencil holes, dual butt thicknesses, internal/external scales for easy marking
  • Durable – anodised aluminium with engraved scales for longevity

These are the go-to angles for everything from frames and mitres to hexagons and octagons.

What else?

  • Quick on-the-go angle marking – conveniently small and perfect for fast access in on-site, or tight spots
  • Sturdy and corrosion-resistant – manufactured from brushed stainless steel and aluminium, combining durability with a sleek aesthetic
