Mag-Mate MX2000 19 Lb Max Pull Force, 5/16" Overall Height, 2.03" Diameter, Ceramic Cup Magnet

Plated, low-profile, cup magnets are ideal for holding steel doors, hanging signs and lights, mounting antennas, retrieving steel items from tanks, vats, bins, and lakes, holding tarps in place, and many other industrial uses. The galvanized plating process on these magnets helps prevent them from rusting. If your application involves a damp/wet environment or repeated contact with moisture, we recommend using a galvanized cup magnet.
