Product  Description

 

Rubber coated magnets, also known as weatherproof magnets, are made by Neodymium magnet, stainless steel and durable rubber coating.

The protective rubber coating protects magnets from chipping, liquid, and corrosion. Thus can be regarded as an ideal solution for both indoor and outdoor holding applications which need high magnetic strength.
