    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: An extendible or adjustable length level is provided. The level includes a locking mechanism allowing the user to fix the level at a selected or desired level. The locking system allows the user to lock the level at the desired length and provides more effective and robust locking than conventional expanding levels. In some embodiments the locking mechanism is designed such that translational movement of the user-actuated control (as opposed to rotational motion) is used to move the locking mechanism into the locked position.
