These hooks were designed to hang up all the garden tools in my shed. In my shed they hang from a section of shirting board that is screwed to the upright beams.
The hooks have countersunk holes in case you need to fix them in place. I haven't found the need and like the freedom to reconfigure my shed more easily.
I made about 15 of the various sizes and hand all sorts from them including a lawnmower. So far they have been in use for about 6 months and are still working 100%.
80% less if you dont need the strength
