Crescent Lufkin L1624RS 16 x 24 Inch Aluminum Rafter Square (Hi-Viz Dual Sided 1/16 Inch Markings Corrosion Resistant Framing Carpenter Layout Tool)

The Crescent Lufkin L1624RS is a 16 x 24-inch high-grade aluminum rafter framing square engineered to execute precise measurement layouts down to 1/16-inch fractional increments. This industrial carpentry tool features a permanent dual-sided Hi-Viz printed scale with a protective clear coat to preserve marking legibility against scratching and abrasive wood dust. Outfitted with a specialized weather-hardened corrosion-resistant silver finish, this lightweight structural layout instrument resolves sightline error constraints and out-of-square alignment issues during complex roof framing, structural staircase construction, and general timber fabrication passes.

Best Used For:

• Structural Roof Framing: Calculating pitch calculations, plumb cuts, and seat notches directly on raw timber rafters.
• Stair Stringer Layout: Marking precise rise and run dimensions uniformly across dimensional framing lumber webs.
• Perpendicular Woodworking Verification: Checking squareness and scribing clean 90-degree reference paths on wide sheet goods or structural framing assemblies.

Key Performance & Safety Features

• Hi-Viz Graphic Legibility: High-contrast crisp indexing numbers optimize text readability under direct sunlight or dim early-morning jobsite environments.
• Dual-Sided Fraction Scale: Embedded markings on both faces of the blade and tongue provide instantaneous SAE data reference without turning the tool.
• Industrial Blade Shielding: Hardened clear protective layer encapsulates printed metrics to prevent scale degradation from persistent friction contact.
• High-Grade Aluminum Matrix: Single-piece structural aluminum core remains perfectly flat over years of heavy use while minimizing total operator pack weight.
• Anti-Corrosive Chemical Seal: Specially formulated silver protective coat seals the base metal against ambient humidity, rainfall, and jobsite chemical contact.

What's Included

• (1) Crescent Lufkin 16" x 24" Hi-Viz Aluminum Rafter Square (L1624RS)

Technical Specifications

Pro-Tip: To confirm your aluminum square remains perfectly calibrated after a hard drops, check it using the classic geometric 3-4-5 tracking method; marking three units along one leg and four units along the secondary leg must span exactly five units across the hypotenuse to guarantee a true 90-degree field layout.
