These things could take your finger off. They are strong. if you need something mounted permanent these magnets are for you. The customer support is great as well. I had to contact them because USPS lost my package and they promptly sent me replacements.

Not sure if they are 210lb pull, but pretty strong magnets. They work for holding on my fog lights.

This product has prevented my fire department from having to drill holes in the cab of one our new trucks to mount it's light bar, this saves time and money, not to mention the chance of water leaks. 210 lb. pound of power is just what we needed to make our light bar stay in place while we are running a call.

Worked perfect to hold down light bar

Wonderful powerful is not toys for children s my nice 7 year-old was strapped between those magnet 190 lb very hard to separate she cried and sure she has to loss the finger nail. Very powerful side down only and hole is ready to use adaptation.
