Swanson"s 47-7/8-inch Wallboard Square has been designed for durability, efficiency and safety. High-grade aluminum alloy construction makes for a durable foundation, while five steel rivets and two steel roll pins accurately secure the 1/4 in. thick, heavy-duty head to the body. The heavy-duty head also offers a 1/2 in. working surface for added stability and ease of use on all material. The 47-7/8 in. body was designed to allow the square to hang freely on 48 in. material. The thermally fused yellow powder paint finish has been applied for increased visibility. Increased visibility translates to personal safety when using this square as a cutting guide.
