This Milwaukee Square Set includes a 7" Rafter Square and a 4-1/2" Trim Square. Both Milwaukee squares feature high visibility laser etched markings that will not wear off after heavy use, and are built from a durable extruded aluminum frame. The 7" Rafter Square features scribe notches from 1" - 6" allowing for quick and accurate marks on lumber, and the 1" cutout helps prop pipe allowing users to cut it more easily on the jobsite. The 4-1/2" Trim Square is 35% smaller in size to easily fit into tight work spaces as well as pockets and pouches. The 1/4" and 3/8" dual measurement heel also allows you to perform quick marks. Both squares are back by a Milwaukee Limited Lifetime Warranty.
