Unique-Bargains 20pcs Black Red Metal Body Binding Post 4mm Banana Plug 3.5mm Thread

20-piece binding post set

This pack supplies twenty binding posts finished in black and red for quick polarity identification. Each unit combines a metal body with a plastic insulating shell and accepts 4 mm banana plugs through a 3.5 mm threaded shaft. The hardware suits speaker enclosures where panel thickness prevents standard cup terminals from fitting.

Capacity and headroom

Twenty posts cover a typical multi-driver cabinet or a small PA rack with channels to spare. The 3.5 mm thread limits use to panels thin enough for the supplied hardware, so very thick baffles may need longer screws. The 4 mm banana aperture handles standard speaker cables but will not accept larger gauge spade lugs or dual-banana plugs.
