Johnson 3748 Contractor Top-Read Aluminum Level, 3 Vials, 48-In.

Johnson's I-beam level is a professional-grade measuring tool designed for accuracy and durability on demanding jobsites. The heavy-duty aluminum frame withstands rough construction environments, and shock-absorbing end caps protect the level if accidentally dropped. This tool delivers reliable levelness readings for construction and installation work.

The standout feature is the top-read window, which allows you to monitor levelness from directly above the work without repositioning the level. The three impact-resistant acrylic vials provide clear visibility, and the vials and cover plates are replaceable, making maintenance straightforward.
