The Sterling DTR-2 Dovetailing Rule is made to fit Starrett 4" double and combination squares that have 1/16" thick rulers. The original Sterling DTR-1 is too thick for these Starrett castings. The Sterling DTR-2 is incredibly handy for checking the squareness of your dovetails to ensure excellent fit and “gap less” joints after assembly. The reduced size of one end of the un-graduated rule allows precise checking of squareness in even some of the tightest “London style” dovetails. Regular size rules simply cannot reach into the spaces the Sterling Dovetailing Rule can. The reduced size length is 2-4 times longer than similar rules for use with thicker stock. The Dovetailing Rule is hardened, precision ground and finished with the same satin Chrome finish as the standard rule.
