For those with a copy-n-paste deficiency:

It looks as though one could pull wire from the spool while the spool-wrap is attached, preventing "spin-off".
At the very least, if removal is necessary for use, it would keep them from unravelling in the truck.
Great idea!
Sell 'em in packs of five for three hots, a neutral and a ground. What size spools will they fit? 14, 12 and 10?
Good luck to you, it looks like you have a winner!
