TDP659 - 7-Inch Aluminum Rafter Layout Square

Precision Layout Tool for Industrial Applications

The Techniweld Aluminum Rafter Angle Square (TDP659) is a fundamental measuring and layout tool designed for professionals in construction, roofing, and industrial maintenance. Manufactured from high-grade cast aluminum, this square provides the rigidity and durability required for harsh job site environments without the weight penalty associated with steel tools. Unlike stamped steel squares that can bend or rust over time, this aluminum body resists corrosion and maintains its trueness, ensuring consistent accuracy for critical measurements.

The tool features deeply molded-in graduations that are integral to the body of the square. This design choice is superior to surface-printed markings, which can wear away under the friction of daily use or exposure to solvents and oils. The high-contrast markings include a full 0 to 90-degree protractor scale, allowing for rapid determination and marking of angles. Additionally, it includes standard hip, valley, and jack rafter scales, making it a versatile instrument for complex framing tasks as well as general geometric layout.

Designed with a thick, lipped edge, the TDP659 serves as an excellent guide for cutting tools. Whether guiding a circular saw through timber or a plasma cutter along a straight line on metal plate, the secure edge provides a stable reference point. Its robust construction allows it to withstand accidental drops and impacts that would compromise lesser tools. For MRO specialists and tradespeople requiring reliable, easy-to-read measurement tools, this aluminum rafter square delivers professional-grade performance.
