The STANLEY 45-910 is a blued steel rafter square designed for layout, marking, and angle work in framing and carpentry applications. Blued steel construction resists corrosion and reduces glare on the work surface, making it a reliable choice for job-site conditions. The square is sold individually and weighs 1.5 pounds, giving it the solid feel needed for accurate layout work without adding excessive bulk to a tool bag. Carpenters, framers, and general contractors reach for this tool when cutting rafters, stair stringers, and roof components where consistent angle reference is critical.
This rafter square is suited for residential and light commercial framing work. It handles common layout tasks including marking common rafter cuts, hip and valley angles, and stair stringer layouts. The compact, single-piece steel construction makes it a standard addition to any framing or finish carpentry toolkit. Its straightforward design requires no calibration and is ready to use directly out of the package.
Designed as a standard rafter square for general framing and carpentry layout applications across residential and light commercial construction.
No installation is required for this hand tool. Framers and carpenters should verify the square against a known reference edge before use to confirm accuracy. Keep the blued steel surface clean and lightly oiled to maintain corrosion resistance over time. Store away from prolonged moisture exposure to preserve the finish.
