Johnson 3878 Magnetic Professional Aluminum Level, 78", Black

Johnson's 3800 I-beam level was designed to be durable and easy to use - so much so that it has been the standard in the industry for over 30 years. Its heavy duty aluminum frame ensures accuracy and is durable enough to withstand even the roughest jobsite abuse, and that frame is protected by shock absorbing end caps if the level is accidentally dropped. The level also comes equipped with replaceable, durable acrylic vials that are impact resistant along with a top read window allowing the user to stand over the work to view the vials. This level's strong magnetic edge provides hands-free use on ferrous metal surfaces. Extruded aluminum I-beam with black anodized finish. Computer machined level edge with strong, full-length magnetic strip. 360 degree reading acrylic yellow barrel vials. Screw-on, high-impact resistant plastic covers with protective lenses. Large, patented, magnified top-read window. Shock-protecting end caps. Frame dimensions: 1 In. x 2-1/4 In.
