I have two sets of BDR Jumbo Pits. These are a large puck made of laminated carbon fiber, with an acrylic cap on each end. Each puck is 2-3/4” diameter, 1-1/14” thick. Threaded 1/4-20 hole, with countersink. Very good condition, with minor scratches.
Simple to use, highly effective in some systems. Can be used as-is for footers, or combine with BDR cones for additional isolation.
NO LONGER AVAILABLE
After review, I have decided to keep these.
