Description

Description: This wall extension jump buckle hook anchor screw is made of high quality 304 stainless steel. It is easy to use, you only need a hammer drill to drill a hole in the wall that is the same size as the expansion pipe. Then put the spreader hook into the hole and tighten the hex nut. It comes with a spring buckle hook that is secured for the hanging items to prevent them from falling off. Mounting method: Drill a hole of the same size as the expansion pipe into the wall with a hammer drill. Insert the expansion hook into the hole, then tighten the hex nut with a wrench. After exposure to force, the shell expands and the tail fin hangs on the wall. Note: Expansion dowels must be installed on a relatively hard surface, and the soft and slightly sloping areas are unstable, such as the limescale floor gap of the wall. All expansion pipes should enter the wall. As long as the threaded part is long enough, the sleeve part becomes deeper and stronger. There may be manual measurement differences.
