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.
Claims20
A level comprising:
- a level frame formed from a metal material, the level frame comprising:
- a base structure;
- a vertical wall extending away from the base structure;
- a vial opening defined at least in part within the vertical wall;
- and
- a longitudinal axis extending between opposing ends of the level frame;
- a level vial supported by the level frame within the vial opening;
- a plastic outer level body coupled to the level frame and defining part of an exterior surface of the level, the plastic outer level body comprising:
- a pair of opposing plastic body segments positioned on opposite sides of the vertical wall and coupled to the level frame;
- and
- an end cap positioned at one of the opposing ends of the level frame, the end cap configured to mount to the level frame and to the plastic outer level body.
