Check the listing for details. 10 RCA Jacks, 6 Position 3 Channel PCB Mount Color Coded, Salvage Freight, New. Condition: New. Listed at 11.99 USD. 1211E5H.36 New Six Position, Three Channel, PCB Mount, Color Coded RCA Jacks. Each bid quantity is for a Lot of Ten (10) Jacks. You may bid / buy any number of lots, up to the total quantity available above. These were acquired at a salvage freight sale, and the labels had been stripped from the boxes (as is the custom at such sales). I looked them over closely with a magnifying glass but there is no marking whatsoever that would identify the manufacturer or the part number -- sorry about that. The quality of the parts, however, is excellent in every way. They measure 1.656" x 1.065" x .735." The RCA jack connectors are spaced on a .560" matrix (both length and width). I will try to get some good pictures to help answer any other questions.
