Published shear holding capacities range from about 4 pounds up to 45 pounds, with several common options listing 25 lb or 45 lb.
Listings show materials such as aluminized steel, steel, plastic, and iron. Finishes commonly include powder coating, while some items are listed with no surface treatment.
They attach to magnetic metal surfaces such as refrigerators, whiteboards, steel cabinets, racks, lockers, toolboxes, and steel doors.
Most are tool-free: you set the magnet on any magnetic surface. Several designs include an easy-off lever or release mechanism so the hook can be snapped on, disengaged, and repositioned without tools.
Descriptions commonly emphasize heavy-duty construction and strong magnetic power, noting durability for holding tools and kitchenware. Multiple reviews highlight strong magnets and effective holding performance.
They’re offered as single-hook units and in multi-packs; examples in listings include 1‑count items and 4‑pack sets.
Some listings state designs "will not damage the surface or leave residue," and others list protective finishes such as powder coating to provide more surface‑friendly contact.
Both open-style hooks and closed (looped) hooks are represented; product descriptions commonly identify these two shapes.
