JTS54HD 54'' Johnson Drywall T-square

Overview

JTS54HD JTS54HD 54" Johnson Drywall T-Square is designed for professional drywall measurement, layout, and cutting applications requiring a reliable, long-lasting straight edge.

Technical Features

• 3/16" extruded aluminum blade: Provides an elevated straight edge that prevents a utility knife from riding up and slipping, reducing the risk of cutting errors and injuries.
• Clear protective anodized finish: Creates a corrosion- and rust-resistant surface layer directly on the aluminum, extending the service life of the tool in job-site conditions.
• Unique rivet assembly: Permanently bonds the head and blade together, maintaining a fixed 90° square angle throughout the life of the tool without adjustment or recalibration.
• Thermal-bonded black 1/8" graduations: Large, bold markings are bonded directly into the blade surface, resisting wear and ensuring long-term legibility in low-light or dusty environments.
• 54-inch blade length: Spans the full width of a standard 54"-wide drywall sheet, enabling single-pass layout and scoring without repositioning.

Applications

• Straight-line layout and marking on drywall sheets prior to cutting.
• Guided utility knife scoring along the full width of standard drywall panels.
• Measurement and transfer of 1/8" incremental dimensions on drywall surfaces.
• Right-angle verification and squaring of drywall panels during installation.
