Four Versions: 12,24,300mm,600mm. The 12 and 300mm size is ideal for work with solid lumber and furniture parts. The 24 and 600mm are intended for cabinetry work in the layout of sheet goods, large cabinet parts, entertainment centers and bookcases.

Precision: On the two outer edges of the blade, there are laser engraved lines every 1/32 , and the blade itself has precisely spaced 1.3MM holes drilled every 1/16. Stick a pencil in the hole, slide it along your workpiece and a perfectly spaced line accurately following the stock edge.

Humanized Design: The inch or metric scales are very clear and readable even for olders and poor lighting conditions. The blade edges are machined to a 45 degree bevel, The beveled design reduces parallax and increases measuring and marking accuracy.

Each T-Square consists of a precisely machined, laser engraved, aluminum blade perfectly fitted to a solid, billet handle with two support lips to prevent tipping and a perfectly machined edge for true squaring.

we prefer the 0.7 and 0.9mm mechanical pencil when drawing spaced lines, it is fine enough to do precision work and not easy to broke compared with 0.5mm, also easier than a wooden pencil.

Premium Quality: Made of high-quality aluminum alloy material, wear-resistant, rust-proof, durable and hard to break. Suitable for architectural drawing design, carpentry, etc.
