Johnson Level Tool JTS48 Aluminum Drywall T-square 48 in

Product Description

The JOHNSON LEVEL TOOL JTS48 is a 48-inch aluminum drywall T-square built for layout and scoring work on full sheets of drywall. The extruded aluminum blade and head are each 1/8 inch thick, giving the tool rigidity without adding unnecessary weight. A unique rivet assembly permanently bonds the head to the blade, keeping the square true for the life of the tool. The clear anodized finish protects the aluminum from corrosion and daily job-site wear. Screened, thermal-bonded black graduations are printed at 1/8-inch increments in a large, bold format that reads clearly in low-light conditions.

The JTS48 is designed for residential and light commercial drywall installation. It spans the full 48-inch width of a standard drywall sheet, allowing a drywaller or carpenter to mark and score in a single pass. The square is equally useful for scribing cut lines on cement board, foam board, and similar sheet goods. It is a standard layout tool on framing and finish crews where speed and consistent squareness matter.

Key Features

• Permanent rivet assembly bonds head to blade, maintaining square registration for the life of the tool

Installation Notes

The JTS48 is a hand-layout tool used by drywall installers and carpenters — no power tools or electrical shutoff is required for its use. Keep the blade and head joint clean and free of debris to maintain accurate registration against sheet edges. Periodically verify the head-to-blade angle against a known reference square to confirm the tool has not been damaged by impact or improper storage.
