Crafted from high - quality 18 - 8 type 304 stainless steel alloy, this security bookshelf and clothes hook combo offers top - notch durability. The back plate and bookshelf are made of 14 - gauge material. The clothes hooks are crafted from a solid bar with a 3/8 - inch (Ø10) diameter and feature a one - piece construction. They come with a 1 - inch (Ø25) swivel trip - ball. When the load exceeds 35 lb (16 kg), the safety hooks snap down automatically, adding an extra layer of safety. The trip - ball socket housing stops the hook from being set in the vertical - up position. The unit comes with six clear mounting holes that can take the supplied 1/4' - 20 or (M6) stainless steel pin - Torx® button head machine screws, making installation a breeze.

Using this product is easy. First, use the provided 1/4' - 20 or (M6) stainless steel pin - Torx® button head machine screws to mount the unit through the six clear mounting holes on a suitable surface. You can place books on the bookshelf and hang clothes on the hooks. Just be careful not to overload the hooks; once the load goes over 35 lb (16 kg), the safety hooks will snap down. For maintenance, simply wipe the unit with a clean, dry cloth regularly to keep the stainless steel looking shiny and prevent rust. Avoid using abrasive cleaners as they might damage the surface.
