Unique-Bargains 4 mm Banana Plug Connector 4 Pairs Black Red

What it is and who it’s for

This set supplies four pairs of 4 mm banana plugs for terminating speaker cables without soldering. The screw-type termination makes it practical for installers and hobbyists who want a reliable connection they can assemble by hand.

Capacity and headroom

Each plug accepts a 4 mm pin and the 38 mm barrel provides enough internal space for typical speaker wire gauges. The screw clamp holds the conductor firmly, but very thick or multi-strand cables may not fit fully inside the housing.

Build quality and daily implications

A plastic insulation jacket in black and red gives immediate polarity identification during wiring. The 21 g total weight reflects a lightweight all-metal contact with a polymer sleeve that resists cracking when plugs are inserted and removed repeatedly.
