POWERTEC Tape Measure Square Check Tool – Magnetic 360° Corner Adapter with Rotating Head for Retractable Tape Measures – Measuring Tool for Cabinet, Woodworking, Frames, Box (71226)

Whether you get this or make your own, the general idea behind these jigs is great. I enjoy building boxes of all types and this little tool helps me check square consistently. It pretty much stays in my shop apron.

My husband is a woodworker and has everything. But he had mention that he wanted some small helpful tools for around the shop. This seams great fast and easy way to check for square on large projects. Hope this help the next person.

Worked fine, takes the guesswork out of verifying squareness on projects.

Item was exactly as described. This will be an extremely helpful tool

Product came in super fast. Can’t wait to give it as a gift to my friend that loves building things.

Works great. My husband loves it and said it will really help with his furniture building.

It works as designed... Simple and effective.

Works perfectly! Definitely good price!
