Amazing caps! We own a restaurant and we purchased used chairs. It took us 3 times to get the right size. Definitely worth it. Easy installation

Good product

Worked great!

Easy installation, nice appearance, good value.

Heavy duty, a breeze to install with small mallet. Good value and great quality! Did the job perfect!

received items promptly and they worked well.

I am updating an old dinette set. Why? A good part of it was rusting but the set was too good to get rid of it. Ive replaced many parts that were metal with plastic to prevent or delay future rusting issues. These work great in the base of both the table and the chairs. Additionally because they are a slightly rough plastic they take paint really well. I sprayed them with a metallic paint in a complementary color to the rest of the set. It makes the substitution of plastic for metal practically unnoticeable.

Not as described. Will slide through a 1 square tube. at best they may fit a 3/4 tube.

Fit into the chrome tube legs on my IKEA sofa perfectly. I was super happy at first. However, they weren’t strong —the flat bottoms sheared off after about 2 weeks.

Solved safety issues on metal bed frames.
