The 54 in. Wallboard Square is made from high-grade aluminum alloy for long-lasting durability. Additionally, five steel rivets and two steel roll pins 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 thermally fused yellow powder paint finish means increased visibility when using this tool as a cutting guide. The 54 in. Wallboard length accommodates larger materials.
