Johnson RAS-1B Aluminum Rafter Angle Square, 7 In.

The Johnson RAS-1B is a professional-grade rafter angle square engineered for precise layout, marking, and cutting work on the job site. This 7-inch aluminum square is designed for carpenters, framers and DIY builders who need accurate angle cuts, cross-cuts and stair calculations. Whether you're ripping lumber to custom sizes, marking board dimensions or laying out rafters, this tool delivers the accuracy and durability required for quality woodworking and construction projects.

Built as the first rafter square to feature a continuous scribing notch, the RAS-1B lets you mark and rip lumber to virtually any size you need. Its solid aluminum die-cast construction combined with CNC machining ensures lasting precision, while the integrated bottle opener provides a convenient break-time feature that sets it apart from standard squares.

Features and Benefits

• Continuous Scribing Notch: Allows you to mark and rip lumber to any custom size, not just preset dimensions, giving you maximum flexibility on every job.
• Solid Aluminum Construction: CNC-machined aluminum body with thick, precisely engineered edges that serve as an accurate saw guide and improve durability.
• Permanent Deep Cast-In Graduations: Markings are cast directly into the metal and will never peel, fade, wear off or smudge, ensuring readability throughout years of use.
• 2x4 Board Dimension Markers: Quick-reference etched markers for standard lumber sizes of 1-1/2 inches, 3 inches and 3-1/2 inches make everyday measuring faster and more consistent.
• Low-Glare Powder-Coated Finish: Protective coating provides a finish resistant to wear and fading.
• Integrated Bottle Opener: A practical bonus feature built into the center of the square for convenience during work breaks.
