Check the true vertical of a door frame or the true horizontal of a wall with the Empire® level 96 in heavy duty aluminum level. This tool features impact-resistant end caps that help protect the vials and frame from breakage during accidental drops. The all metal frame of the Empire® level 96 in heavy duty aluminum level resists warping and corrosion for a long lifespan. Tough, acrylic E-BAND™ vials help improve the visibility of level and plumb readings by highlighting the edges of the bubble. Like many Empire® level anodized frame box beam levels, this tool features vial surrounds that let you view the vials in dim and bright lighting conditions. The True Blue® vials are fog and break resistant for long lasting use. Shatter resistant lenses prevent vial damage and are replaceable. The top read window on this Empire® level professional I-beam level helps ensure easy overhead viewing of the vials.
