POSI-LOCK-T-SQUARE-GROUP

Accurate angle layout on larger panel projects challenges even the most skilled woodworkers. You can try extending lines started with a small protractor, but even tiny errors keep growing the further your line extends. Woodpeckers Posi-Lock T-Square, delivers unparalleled accuracy in your panel layout work. Just snap the head in to the angle you want and strike your line.  The head adjusts from 0° to 70° and locks solidly every 5 degrees (plus 22-1/2° and 67-1/2°), giving you a precise angle reference 12-, 24-, or 32-inches long. No other adjustable T-square gives you the range of angles and the positive indexing you get with the Posi-Lock.

An adjustable T-Square with a lot of possibilities…

The secret to the Posi-Lock T-Square is the series of precisely machined indexing holes and the spring-loaded, tight-tolerance indexing pin that meshes with them. The pin snaps into place giving you the confidence to know it is spot-on accurate. 

Even when you’re not working with angles, this is a lay out tool you’ll reach for on almost every project. The blade features the same exclusive “saw-tooth” design scribing notches found in our new Stainless Steel Precision Woodworking Squares. There’s a notch every sixteenth-inch all along the blade. Just drop your pencil in the notch and slide the head along the edge of your stock for a perfectly parallel line. 

The Posi-Lock T-Square also functions as a hook rule, giving you a positive reference from the edge of your stock. Both edges of the blade are laser engraved with an inch scale in 1/32” increments. The graduations are held to a tolerance of ±.004" total accumulated error over the length of the blade. The thin, satin-finish stainless-steel blade is easy to read and minimizes parallax error. 

The Posi-Lock T-Square comes in 3 blade lengths, 12, 24 and 32 inches.  Each one comes with a wall-mountable Rack-It™ to keep your Posi-Lock handy, yet out of harm’s way. The three sizes are available individually, or you can buy the complete set including three Posi-Lock Rack-Its™. 

Like all Woodpeckers Tools, the Posi-Lock T-Square is precisely machined and carefully inspected in our Strongsville, Ohio factory (just south of Cleveland). Next production run expected to ship in early 2026. Order yours today!
