4 pieces / 2 Pairs of New Pomona MDP-S Double or Dual Banana Plug Connectors.
4 pieces or 2 pairs of Pomona MDP-S Double or Dual Banana Plug Connectors, with shorting bar. The photo shows a pair, but you get 2 pairs or 4 of them. Seem to be new / NOS, but I don’t know 100% for sure. Super clean, though. Free shipping in the US. I have a lot of these, so if you need a bunch, make an offer for a bulk deal.
