Great Purchase
Used this over this summer for many home improvement projects and some custom builds too. Not only for drywall but also for some larger wood construction projects. It's a great tool, period.So far it's performed flawlessly. Great deal for the price, straight and true, and the T is square - perfect 90 angles. I have no issues or complaints. I wouldn't hesitate to purchase this item again if I needed to, and I have already recommended it to some friends.

Amazing value
I can't believe this product is available at this price point with no assembly needed. In order to ship this I was expecting them to send it with hardware to assemble. Instead a massive box showed up with this preassembled T-square ready to go. For the price of the item and the high quality and the cost of shipping a large box it's overall an amazing value.

Heavy Duty
I got this to use measuring and cutting drywall for a basement remodel. This tool is sturdy with clear, easy-to-read numbers. The cutting edge has a nice lip that prevents the drywall knife from hopping or skipping. The 90 degree angle stays nice and true after repeated use.

Well Made
Very nice product and very well made. 54 in is great because you can cross the line on an 8-ft piece of sheetrock when drawing lines. That's the specific reason that I bought this. It did have some Nicks and dings from Shipping where something sharp cut into it that needed to be filed. Only reason I gave this four stars is because after I bought this for about $25 I found the same thing at Home Depot for $12. Never thought I would have seen that at Home Depot for that price so I didn't even think about price shopping. Still, very happy with my purchase have been using it daily rebuilding a couple of rooms.

great tool
It is likely cheaper bought locally but it is a great T. It is heavier by a considerable amount to the one I bought at the big box store.

Heavy Duty for sure!
Little heavier than anticipated; but perfect for using rotary cutter to cut longer pieces of fabric

works well
I used this to cut insulation for my garage door. Helped keep things nice and straight. Worked very well. Now, I need to figure out where to store it as it's big.

A great long lasting T-square
I purchased this item for my wife so she wouldn't keep borrowing mine for her crafting. I have used mine for years for multiple shop projects. It is well crafted. I have found many uses for it with either home repair projects of my woodworking projects.
