## Description

Female to Female Standard 4mm banana plug adapter for connecting to 4mm male to male banana jack leads. Packaging: Black 4mm Female to Female Jack Insulated Banana Connector * 5Pcs Red 4mm Female to Female Jack Insulated Banana Connector * 5Pcs

Review: Good, Tight Connectors - I needed female to female banana connectors to go with some test leads to be used with my multimeter with Powerpoles on one end and banana plugs on the other. In order to use as an in line ammeter, I need to connect two set of leads together on one side with a female banana connector. I ordered this red and black package, and these connectors fit just as I needed. They are tight, which in my case is good as I do not need the test leads to come apart while doing measurements. Overall, pleased with performance and value.
Review: Works with Linn LK85 Amplifier - Bought a Linn LK 85 amp on ebay. Recieved it and much to my dismay, the speaker terminals were unrecognizable! Searched the internet and found reference to these on an audio forum. Plug these into the terminals and then the banana plugs go into the end of these. Perfect solution!
