Abstract
A level and level-straightedge system is provided. The level may include one or more slip-resistant structure. The slip-resistant structure may be a collar formed from a high friction polymer material that at least partially surrounds a level vial. The collar may be co-molded with the material of the vial surround. The level may be a relatively small level having a length less than 14 inches and may include a groove for receiving a straightedge. The groove design alone or in combination with the collar may allow for a relatively short level to support a relatively long straightedge.
