Frequently asked questions

Why epoxy instead of a regular nickel-plated magnet?

The epoxy layer protects the magnet better against moisture and condensation, making it less likely to rust. For dry indoor spaces, a regular NiCuNi magnet is sufficient.

Does this magnet work through wood or plastic?

Yes, through a thin layer. Because the magnet is only 2 mm thick, the force decreases quickly with distance. See can magnets work through wood and glass?

How do I attach them?

With two-component adhesive in a routed slot, or with double-sided tape on a smooth surface. More tips in how do you mount a magnet?

Safe use
