This double-locking suction hook makes an ideal, temporary hanging solution. Just mount the suction cup on any smooth, flat, nonporous surface, lock it in place with the flip-down locking mechanism, and the hook will hold up to 5 lbs [2.25 kg]. When you also flip the hook to hang downward, the heavy-duty rubber suction cup will support up to 10 lbs [4.5 kg]. Temporarily hang towels, bathrobes or potted plants. When you're ready to move on, simply flip the locking mechanisms up to release the cup and the double-locking suction hook goes with you, providing a convenient, portable hanging solution.
