Johnson Level Tool 575 Line Level 3 Inches Structo-cast

Product Description

The JOHNSON LEVEL TOOL 575 is a 3-inch line level built for trade professionals who need a reliable, lightweight leveling reference on a taut string line. The vial housing is constructed from Structo-Cast plastic, an impact-resistant material that keeps the tool light enough to minimize line sag during use. Unrestricted hooks allow the level to slide freely along the line without having to remove and reattach it at each measurement point. Designed for fast, repeatable leveling checks, the 575 is a standard hand tool for masons, landscapers, and sheet metal workers.

The 575 is suited for residential and commercial applications where a string line is used to establish grade or alignment. Common use cases include laying masonry courses, establishing landscape grades, and aligning sheet metal installations. The lightweight Structo-Cast body reduces the downward bow in the string that can introduce leveling error, making it a practical choice when the line must span longer distances between anchor points.

Key Features

• 3-inch impact-resistant level vial for clear, accurate readings
• Structo-Cast plastic construction reduces weight and minimizes line sag
• Unrestricted hooks allow free sliding movement along the string line
• Suitable for masonry, landscape grading, and sheet metal work

Compatibility

Designed as a standard string line level for use in masonry, landscaping, and sheet metal applications where a lightweight, hook-mounted vial level is required.

Installation Notes

Hook the 575 onto a taut string line at or near the midpoint between two anchor points for best accuracy. Ensure the string line is properly tensioned before reading the vial, as excessive sag will produce an inaccurate level reference. No tools are required for attachment or removal. Store the level away from impact hazards to preserve vial integrity over time.
