General 676 Precision 6 Rigid Stainless Steel Rule
The Polystyrene Level Ruler by Mayes is both a level and a ruler, with plumb and level vials (accurate to 0.001 inch). Made of lightweight and durable high impact composite polymer (just over 3/8 inch thick), it has easy-to-read numbers and tapered ruled edges for closer measurement. Use the center-finding edge to hang pictures, shelves, and more, center it, then check for level. The compact size makes it easy to take anywhere.
