CESS Black and Red Banana Female Jack Socket - 4mm Banana Female Connector Panel/Chassis Mount Soldering Type (10 Pack)

Excellent quality. Will buy more.

These are good sockets, well worth getting. They’re very easy to work with, take solder well, and seem to be well built.

I needed a couple of 4mm banana jacks to replace broken plastic ones on a light fixture. These have a nice metal jacket that provide better structural support than plain plastic, and you get a bunch of them shipped to your door for very little money. The center conductor terminates in a very heavy solder terminal that looks like it'll carry quite a bit of current. Unfortunately, the terminal is chromed and thick which makes it very difficult to get it hot enough for the solder to bond without applying heat for so long that the barrel melts. It's not impossible but there's a very thin margin of success with these terminals. In hindsight I could have improved my result by turning up the temp on the iron a bit and prepping the terminal by removing some chroming and tinning it in advance of soldering, but by the time I figured this out the terminals were already done. This may seem like a negative review but I'm really just trying to relate my experience. These are decent quality for the price and if I need more I'd buy them again.

These are really high quality. They hold the banana plug firmly but not too tight that it’s irritating. They’re easy to attach and the exterior-facing plastic covers look good. Only areas to improve: they’re a little long, and the hole at the end to attach wires through is pretty small.

Good product. Exactly as described. Works well.

Created a box to keep my O2 consontrator running longer with a LIFEP04 12V battery. Used the banana jacks to connect to a charger. They are used often and are still have a tight fit.

Sealed packages of 10; 5 red + 5 black; Large solder tabs sized for up to #14 wire. Mounts in 5/16 hole in equipment panel up to ~1/4 inch thick. Front bezel protrudes 1/8 inch in front of panel, overall depth is 1-1/8 inch

I purchased here on Amazon Monoprice brand gold plated banana plugs and connecting them to this female jack socket. The connection is solid, no play at all.
