What Customers Are Saying

Customers overwhelmingly praise this combination square for its accuracy, solid construction, and reliability in woodworking and trim work. Most highlight its precision, noting it doesn't wobble like cheaper alternatives and performs exactly as expected. The American-made design is appreciated for its durability and lightweight, compact form that fits easily in tool belts.

Solid Tool That Does Exactly What I Needed

Would Recommend

I bought this 16-inch adjustable square because I wanted something more accurate than the cheap plastic squares I'd been using.

Great New Tool - Works Great So Far

Would Recommend

I love the small combination T-Square with Level and built in removable scriber. It all works great as designed. It compares closely to my Dad's old one where the base of the unit is longer (about 4") and it dates back to "very old". Looks like it is made sturdy and may last as long as my Dad's. It is still working but I can't find the ruler I removed and misplaced somewhere. Wish it was made in U.S.A.

Does the job, but the metal is a little sharp.
