Product Description:

Best resistance to rust and corrosion, suitable for both indoor and outdoor use

Easy to use: You only use a hammer drill to drill a hole in the wall that has the same size as the expansion tube. Then insert the expansion hook into the hole and tighten the hex nut.

The expansion is created by tightening a threaded bolt that draws a conical cone that extends a sleeve against the wall of the hole.
