Here is a side view of the plate that was under these rope clutches. These things are worth their weight not only for the strength they provide the clutches, but they will save my head from serious damage. Remember these clutches are right over the galley and the ice box, both locations are highly frequented by myself and other people of similar or taller height. Acorn nuts are not enough protection from injuries to your head. This one is 3/8" thick total and the tapered nuts are flush to the surface. So even if your head is sliding along the overhead you are not likely to hurt yourself on the plate or the tapered nuts holding the clutch.

I suspect that someone had this thing made.
