Common options include 5, 8, 10, and 13 hooks.

Designs include expandable accordion or diamond-shaped frames that open and close, retractable hooks that slide back into grooves, and folding hooks that fold down for use and fold up to save space.

Reported capacities vary: one wooden accordion lists a load-bearing capacity of up to 10 kg; several metal flip/rail models state "Holds up to: 40 pounds;" and a folding hook rack lists holding up to 35 lbs when mounted into solid wood or studs.

Most are wall-mounted. Listings vary between "No Assembly Required" and notes that adult assembly or tools may be needed; several descriptions state that mounting hardware (screws or anchors) is included.
