The Swanson 47-7/8 in. Aluminum T-Square is a lightweight model of our TD124, featuring an 1/8 in. thick design that’s perfect for DIY work. High-grade Aluminum alloy construction makes for a durable foundation, while five steel rivets and two steel roll pins secure the head to the body. The head also offers a 1/2 in. working surface for added stability and ease of use on all material. Its 47-7/8 in. body was designed to allow the Square to hang freely on 48 in. material without snagging. The thermally fused yellow powder–paint finish increases visibility and creates contrast against black gradations for easy readings. With all the functionality of our heavy-duty T-Square in a lightweight design, this Square gives you the features you need at a great value.
