The Woodpeckers TS-24-20 Precision Woodworking T-Square - 24 Inch With Rack-It (Model TS-24-20) is a precision layout square built for woodworking. This is a T-square designed for marking, scribing, and squaring parts accurately off the edge of your stock, especially when you want repeatable layout without measuring and re-measuring.

The big advantage of this layout square is speed with control. The blade has precision drilled scribing guides spaced every one sixteenth inch along the length, so you can drop in the tip of a mechanical pencil and slide the square to lay out a dead-parallel line. It also has one quarter inch diameter holes on one inch centers for quick shelf-pin layout and other consistent spacing jobs.

Woodpeckers builds these as two critical parts that work together: a precisely machined, laser-engraved aluminum blade fitted to a solid billet handle. The handle includes support lips that help prevent tipping, and the beam design includes a lip that rests on the top surface of your stock to help keep the tool from rolling like many T-squares do.

Reading your marks matters, especially on sheet goods. The outer edges are beveled to 30 degrees to bring the graduations right down next to the workpiece edge. The scales are laser engraved to a tolerance of 0.004 inches, so the markings stay crisp and consistent for layout work where small errors show up fast.

On the durability side, the blade and handle are secured with precision socket screws (quantity varies by blade length) and the hole pattern is slightly offset to keep constant tension between parts. That gives you solid performance in use, and it also means the blade can be replaced if it gets damaged instead of scrapping the whole square.

If you build cabinets, bookcases, and casework, the 24 inch length is the sweet spot for a lot of shop layout tasks on larger parts. And since it ships with the wall-mountable Rack-It, you can store it where it will not get buried under clamps and offcuts.
