New heavy discounts for higher quantities! If you order 4 you'll get an additional 28% off compared to ordering one! This sturdy welding square is an excellent tool for any welder or maker (works great for wood too!). These squares are laser cut from quarter-inch thick steel with better than 0.005" tolerances. The square is highly accurate and strong. It has cutaways to allow for ideal clamping and the 90º corner is relieved to allow access to the inside corner of the material being squared. The short sides are 8.5" long and the long side is 11.5" long. The square's sides are exactly 2" thick and perfectly perpendicular to the main web which works great for squaring against a work bench or table when the square is on its side! It ships flat-packed (unassembled) OR pre-assembled (see below), assembly is simple and fool-proof. The precision laser cut tabs and notches perfectly align all of the pieces; add a few tack welds in the recessed slots and you are good to go! The squares ship with detailed instructions and pictures. I NOW OFFER PRE-ASSEMBLED SQUARES!! I now offer squares completely assembled, welded, and ready for use!
