Mike, the owner of erstwhile Lightning Bolt, had solved this problem by
designing a wire-to-spreader fastener that consisted of several short
pieces of concentric heavy walled synthetic tubing of some sort (I
believe the outer tubing was truck air brake lining.). The tubing
assembly was mounted on the band of a hose clamp by another short piece
of concentric tubing, if I recollect correctly. The flexible concentric
tubings were mounted to the spreaders with the hose clamp and the quad
wire passed through the tubings. It made for a nice neat, taut
assembly and the positions of the wires could be adjusted easily by just
moving the hose clamp and without drilling holes. They worked and
continue to work very well.
His wife used to make them up for him and he sold them for about
$1.50-2.00 each.
