SOLDERLESS 1/4" TS PLUG: Terminate speaker, guitar, and mic cables without a soldering iron. Strip the wire, loosen the screws, insert, tighten. A small Phillips screwdriver is all you need. TS MONO, STANDARD 6.35mm: Tip-Sleeve mono configuration. Fits any 1/4" jack on guitar amps, powered speakers, mixers, patch bays, and audio interfaces. Two-pole design carries a single audio channel, instrument or speaker level. SCREW TERMINAL, NO SOLDER: Loosen the two terminal screws with a Phillips. Insert tip wire into the + terminal, sleeve wire into the - terminal. Tighten. Polarity marks on the body keep you from wiring backwards. No iron, no flux, no shrink tube. GREEN HOUSING, BRASS CONTACTS: Green body stands out in a cable loom or behind a rack, so you grab the right cable fast. Brass contacts handle the signal path. Housing snaps closed over the terminal block to protect the connection. FOUR PLUGS FOR MULTIPLE CABLES: Build or repair four cables in one sitting. Make a pair of speaker cables and keep two spares. Or build a set of patch cables for a pedalboard. Four plugs cover most small jobs without a trip to the store. ~NANYI TS 1/4 Inch Jack, 6.35mm Mono Male Plug for Guitar/Speaker/Microphone Cable That can be Solderless Screw -4Pack
