The right angle banana plug connectors worked great in a low profile application on my boat's 12v lithium batteries. The connectors allow for a quick disconnect for battery charging.

Easy to install excellent materials

Price has doubled since I bought a 10 pack 3 years ago. Still worth it. These are better than the nicer looking PID #2801 which I have purchased previously as well. I would not use those anymore as the banana plug part of it is not well made and you have to mess with the blades to get them to fit into jacks snugly.

Pros:
1. Space saving when you are needing to back something up against or very close to something (say receiver up to cabinet or house wall),
2. Insulating. Unlike the PID#2801 plugs which seem to fit loose in the jack and like to touch each other. These have the nice rubber/plastic insulating covers. You will not be shorting these together with other connectors.
3. Easy to connect wires. These are not as picky on getting the wire stripped to some exact length like PID#2801. These have some room for error as long as the bare wire covers the distance from the first screw to the second screw, you are good.
4. Solid wire connection. Once you have torqued down the screws, that wire is not coming out. Plus the red/black cover keeps the set screws from backing out. PID#2801 has too many pieces that you tend to only get finger tight. The banana plug part unscrews itself and it is not easy to tighten down the wire side with just fingers.

Cons:
These are the best I've used but there are some cons.
1. You have to have a small flat blade screwdriver to tighten the set screws. Not a problem for most people buying these but keep that in mind if you are not properly equipped with tools.
2. Puncture wounds. I've wired up at least a couple dozen of these. You are using a small flat blade screwdriver and torqueing down pretty good. Blade slips out of slot and often proceeds to puncture your finger. No matter, these are still my favorite of all I've tried.
3. You do have to remember to put the red or black sleeve on the wire before connecting the wire. And get them properly color coded with your wire polarity. For some of us, that is a lot to remember.
4. Depending on the connector density of your wall jack/plate (I am using the 5 speaker PID#3539), these can take a bit of work to get them to fit around other connections. But I did get them to work with two of those plates in a somewhat restricted space (PID#34376).

These are the only plugs I will use anymore. Don't even bother with most others.

Great product, great price.
So pleased, I've just ordered more.

Works well, as advertised. Perfect

I love these. Makes speaker connection to the back of my AVR much easier and neater Also allows my entertainment cabinet to be closer to the wall.

These are the only banana plugs I'll buy. The right angle design is superior for space saving compared to any other design.

These are very easy to use. Pull the sleeve off. Undo the tiny screws. Put your stripped speaker wire into the sleeve and then into the plug. Finally, tighten down the the tiny screw and pull the sleeve back up. Done.

Good quality plugs. Very easy to install.

Very good quality, sturdy, professional looking and reliable snug fit

A bit on the pricey side but if you need it like I did they were great. I used them as cross connects behind the 4 speaker plate. To make the series connection without all the extra ( single cables).
