Frequently Asked Questions

Q: What surfaces will this magnetic cup holder stick to?

A: The magnetic cup holder attaches to any flat ferrous (iron or steel) metal surface such as boat rails, car doors, refrigerators, metal shelving, gym equipment, and workshop benches. It will not stick to non-metal or non-ferrous surfaces like aluminum or stainless steel that lacks iron content.

Q: What size cups or bottles does this holder fit?

A: The holder features a 3.5-inch diameter coaster and 3.5-inch height, making it compatible with most standard cups, cans, water bottles, jars with sleeves, and tumblers. Oversized mugs or very wide-base bottles may not fit securely.

Q: Will the magnet scratch my surfaces?

A: No! The super-strong magnet is wrapped in a protective black rubber coating that prevents scratches on your metal surfaces and protects your fingers from pinching.

Q: Is this cup holder waterproof or rust-resistant?

A: Yes. The holder is made from carbon steel with a thick electroplated finish that resists rust and corrosion, making it ideal for outdoor and marine environments like boats and docks.

Q: Does it require any tools or installation?

A: Absolutely not. This is a tool-free, no-drill solution — just place the magnet against any compatible metal surface and it holds firmly on its own. It detaches just as easily when you need to move it.
