The Magnetic Combination Square hand tool features a magnetic locking system. The tool is suitable for a variety of applications including carpentry, general construction and remodeling, woodworking, and do-it-yourself projects.

Unique to the square is a smooth-sliding head and patented adjustable magnetic locking system that features a rare earth magnet. The rare earth magnet ensures a secure, reliable hold. Easier and faster to adjust than similar tools with locking thumbscrew designs, the system enhances efficiency, while ensuring precise alignment and accuracy. Additionally, the user-friendly aspect opens up the tool to all end-users, professional and novice. The product is built both durable for job sites and home workshops, as well as designed to provide professional results every time. Featuring hardened, cast-zinc construction, the body is rugged and corrosion-resistant. The 12-inch reversible ruler is durable stainless-steel, and finished with easy-to-read graduations in both 1/16- and 1/32-inch increments. For enhanced accuracy, the square is machined on five sides, and all edges are milled. A magnetically-held hardened scribe and reference vial are also included.
