This is a pragmatic, simple, wall mountable slide hook that provides pretty good levels of vertical strength. The hook space diameter is a hair above 2" (51mm). You can easily hang a heavy jacket or purse from this hook attached with a single screw or long nail in drywall.

The wall grip is held to the wall with a single nail or screw (hole is 2mm) and the hook to slides in securely from either side.
