On the two hook my 3-part aluminum folding ladder hanging on the garage wall; makes a very strong impression, for aluminum ladder more than adequate. Fastening with 2 anchors should overwhelm anyone. Whether she's so galvanized that it does not rust, I do not currently - and probably in the future not because it is mounted on the garage inside ... Why only 4 stars? A 3-stage ladder is usually wide to 15cm at the bottom, so it would be great if the inner surface would be slightly wider; it really fits exactly to the millimeter and you have a little "reprints".
