## Questions & Answers

**Q: Will banana plugs fit in the hole on the top? Please don’t say “you can use the wire directly” like you’ve done twice. That is not what the question**
A: I measure the hole at the top as 5/32" or 3.9 ish mm. That should work with most banana plugs but I don't personally use them with my speakers. The hole is more than deep enough also as it run from the top to the bottom of bare wire hole.

**Q: Will these posts accept a banana plug?**
A: It’s a yes or no question. Why do you refuse to answer the question? People who use banana connectors do NOT want to wire directly. Just say “no” if that’s the answer.

**Q: Will banana plugs fit in these?**
A: These are standard cups. You can use wire directly, lugs, or banana plugs. You have to realize the seller is some Chinese guys who doesn't speak English.

**Q: This discription and picture are trash... why is the diameter of the cut out needed not listed? Its more important that screw spacing!!**
A: It looks like it is listed it’s a three inch diameter 
I used them to replace the old Spring loaded 
Connection ,screw holes not a problem

### ⭐⭐⭐⭐ Great Value - They Work, Be Careful
*by K***K on April 29, 2023*

Great value, and they work. Easy install. Two issues. One, the terminals are super thin. Be careful when installing the spade connectors. Two, plan on buying the banana connectors if you intend to disconnect/connect often. It's a PITA to tighten the lugs due to the size and angle of the hand nuts.
