I installed 3 pairs of these in 2 different apartments. They are ideal for hanging long extension ladders and tall ladders. They hold the stairs firmly and securely, nestle snugly against the walls and do not interfere with each other. Measure carefully before installation to hold something long, e.g. B. a ladder. It is best to mount them directly into the studs using the screws provided. Otherwise, I recommend using lever bolts instead of simple dowels. Pivot pins are better suited for securing loads that they can handle.
