MX 4mm Banana Male Connector SP-14 Red and Black Pair (MX-2775)

The SP-14 body style is one of the common 4mm banana plug shapes, and this pair comes pre-matched in red and black so a power lead's polarity is marked the moment the plugs go on, without needing separate coloured sleeves or labels added afterward. Buying the pair together also guarantees both plugs actually match in size and fit, which isn't always a given when sourcing two single plugs from different batches. A straightforward, ready-to-use pair for building a basic bench power lead from scratch.
