Johnson Level Tool 1817-0000 Architect Scale Ruler 12 in

Product Description

The JOHNSON LEVEL TOOL 1817-0000 is a 12-inch aluminum triangular scale ruler designed for architects, designers, and drafters who need accurate scaled measurements on plans and drawings. Constructed from extruded aluminum with an anodized finish, it resists wear and corrosion through regular job-site and office use. Graduations are laser etched for long-term legibility and precision. The ruler carries ten U.S. standard architectural scales on three faces, with individual divisions down to 1/16 inch, making it a reliable go-to instrument for reading and marking scaled construction documents.

This triangular scale is suited for residential and commercial architectural drafting, plan review, and field takeoffs. It covers a full set of common architectural ratios used in construction drawing sets. The anodized aluminum body keeps the tool lightweight while maintaining structural rigidity through repeated use. Architects, engineers, interior designers, and construction estimators will find it fits standard drafting workflows without modification.
