Johnson Level Tool 575 Line Level 3 Inches

Product Description

The JOHNSON LEVEL TOOL 575 is a 3-inch line level designed for tradespeople who need fast, accurate horizontal readings on a stretched line. Its lightweight Structo-Cast body minimizes line sag, which is the leading cause of inaccurate level readings when spanning long distances. The unrestricted hooks slide freely along any string or mason line, allowing quick repositioning without removing the level from the line. Built for jobsite conditions, the impact-resistant housing holds up to repeated handling and rough storage.

The 575 is suited for residential and light commercial applications where a level reference line is needed across an extended run. Common use cases include setting batter boards for foundation layout, aligning fence posts, establishing grade references, and leveling suspended runs of conduit, pipe, or duct prior to final support installation. The compact 3-inch length keeps pack weight low when carrying a full toolbox or service bag.

Installation Notes

Line levels are typically used by carpenters, masons, plumbers, and general tradespeople during layout and rough-in stages. Hang the level at or near the center of the line span to minimize deflection error. Ensure the line is pulled taut before reading the vial. No tools or fasteners are required for attachment.
