magnetic door hanger

Capacities vary widely. Small single-magnet holders are around 4–4.4 pounds, while heavy-duty hooks list about 25–28 pounds. Some products provide separate ratings by orientation or surface (for example 28 lb vertical vs 10 lb horizontal) or different values on steel versus glass (about 5–10 lb on steel vs 2–5 lb on glass).

Common materials include aluminized steel, steel, aluminum alloy, iron, and powder-coated metal, with some decorative pieces made from solid wood. Several magnetic hooks specify neodymium magnets in their construction.

Some magnetic hooks perform noticeably better on ferromagnetic steel than on single-layer glass. For example, one wreath hook lists about 5–10 pounds on steel but only 2–5 pounds on single-layer glass. Other products may also provide separate surface- or orientation-specific ratings (vertical vs horizontal).

Common configurations include single open hooks, double hooks (two hanging points), and multi-hook racks (for example six key hooks with a small shelf). Products are also sold in multi-packs of single hooks; the set includes single-, double-, and six-hook designs.

They attach to ferromagnetic steel surfaces such as steel doors, refrigerators, lockers, and cabinets. Some designs can also attach to single-layer glass, but thicker double-pane glass and non-magnetic surfaces (like wood or aluminum) are generally not suitable.

Most install without tools — simply place the magnet on a compatible metal surface. Some hooks include a lever or an "easy-off" release that lets you lift and reposition the hook without drilling or damaging the surface.
