The Empire® level 36 in aluminum level combines strength, lightweight, ease of use and accuracy in a professional quality measuring instrument. The rounded, beveled end caps level are made of high impact plastic to protect the tool from damage due to dropping or rough handling. Three durable acrylic vials are shielded within the rugged I-beam construction and the center vial is viewable from above through the convenient window. The USA-built Empire® level 36 in aluminum level has ergonomic grip zones for comfortable handling and is assembled with machine screws, not clips or rivets. The aluminum frame is given the distinctive Empire® blue anodized finish, adding value and pride of ownership to the accuracy and reliability of this simple yet vital tool.
