These strips at Radio Shack can be easily cut into 12 terminals to make tip spacers. Since you
will need 20 terminal strips for tip spacers and several more for support cords and 20 meter
spreader anchors, you will have to get three such packages. These will make it easy to adjust
for the various functions. Get the jumbo size to make it easy to insert the wire as well as the
cord for the tip spacers.
I painted mine with the same color used on the spreaders.
