Our 4-1/2 in trim square is an everyday carry layout solution. The compact square is 35% smaller in size to easily fit into tight work spaces as well as your pockets and pouches. High-visibility laser etched markings will not wear off after heavy-use, providing you with consistent high-visibility throughout the life of the square. A 1/4 in and 3/8 in dual measurement heel also allows you to perform quick marks. The trim square is backed by our MILWAUKEE® limited lifetime warranty.
