7-Inch Aluminum Rafter Square for Carpenters
The Johnson RAS-1 is a 7-inch aluminum rafter angle square built for general carpentry tasks. Its solid cast-aluminium body provides a rigid reference for layout work on framing and trim projects. Permanent moulded graduations and a low-glare powder-coat finish keep markings legible in bright conditions. The tool suits professionals and DIY users who need a durable, multi-function layout square.
CNC-Machined Edges and Thick Saw-Guide Profile
Exclusive CNC-machined edges deliver consistent accuracy for marking cut lines and checking angles. A thick body edge doubles as a reliable saw guide when cutting dimensional lumber with a circular saw. The protective powder coating resists corrosion and reduces surface glare during outdoor use. An included instruction manual supplies rafter tables for quick roof-pitch reference.
Verify 7-Inch Size Fits Your Layout Needs
Confirm that a 7-inch blade length matches the scale of your typical framing and stair-layout tasks. The square functions as a ruler, protractor and rafter-layout tool but does not replace longer straight-edges for full-sheet work. Buyers who need extended reach for large-panel marking or wider stock should consider a larger square. No batteries or calibration are required for operation.
