We have launched the DTR-5!
For those woodworkers without smaller squares we have now made the DTR-5 which is designed and made for popular 12″ cobination squares that most woodworkers have in thier toolkit. The DTR-5 is .089″ Thick and .445″ tall on the larger end and .090 on the smaller end. We have tested its fit on several vintage and modern 12″ Combination sqaures like Starrett, Brown and Sharpe, PEC and others. While we cant garuntee that it will fit ALL 12″ combination sqaures it should fit most.
