Rafter squares are an essential part of any carpenter's measurement tools and equipment. Whether you are working on rafter layout or just need a quick 45deg or 90deg angle measurement, EMPIRE® is committed to delivering the most refined, accurate, and easy-to-use layout square. Our TRUE BLUE® rafter squares deliver on our commitment and legacy of providing quality measurement solutions while our other rafter squares deliver a full line of solutions to meet any measuring needs.
