Cal was very helpful and even included a sample set of magnets in my order to help me evaluate the magnets best suited to my needs. Highly recommend!

They worked perfect for a cabinet I built to hold a heavy door closed.

Second time ordering. Complete satisfaction. Thank you.

Found what I needed quickly and received it in a timely manner.
Performed as expected and I'll be ordering from them again.

I bought these with idea of using all 12 magnets on a 2.5" dust collects coupler (6 on each side) on my DeWalte table saw. I drilled 6 holes on each coupler, but tried it with 3 magnets on each coupler to see how strong the magnets really are.
Very strong!
I literally had to twist the couplers apart in order to separate them, these would not pull apart easy.
Since I only needed 6 magnets for one set of couplers, I now have 6 more magnets to build another set of dust collection couplers.
