Ruler Stop (Orders accepted but out of stock until 10/15/2020, our apologies for the inconvenience.)
The Czeck Edge Ruler Stop is the only one of it's type on the market today. The three block design allows it to be used to accurately and easily mark from a fixed edge, check diagonals to assure box squareness, and many other uses. No apron pocket or shop should be without one. Please click photo below for more info and to purchase!
