Light, compact, adjustable, and deliciously accurate; the 100mm Starrett 13MA double square is the perfect tool for checking fine joinery. The facility to slide the unwanted length of the blade out of the way is invaluable, when checking the outside shoulder of a rebate or tenon for example.
As you would expect from Starrett, the accuracy is well within workshop grade B. Both sides of the hardened steel blade are engraved with full mm on one edge, and half mm on the other.
Please note: the blades and heads of Starrett double squares are not interchangeable with Starrett combi squares.
