Abstract: A tool, such as a level, including one or more polymer/plastic body segment, protective cover and/or seal is provided. The covers discussed herein may limit or prevent dirt or construction materials, such as concrete, from entering into the level body. The cover may also be a non-stick material, such as a polymer outer sleeve, that limits the ability of dirt and construction material to adhere to the level. The level may also include scratch resistant vial windows.

Abstract: A level including a rotating level vial is provided. The level includes a locking mechanism that utilizes an actuator that engages a brake to lock the rotating vial into the desired position. The locking mechanism may include a spring element that is compressed by the actuator during locking, and the spring element in turn pushes against the brake facilitating control of the normal force that the brake applies to the vial surround of the rotating vial. The rotating level vial may engage the level body such that the rotating level vial is permitted to rotate 360 degrees in both the clockwise and counter clockwise directions.
