Review on Posi Tap Mini Connectors Gauge Wire by Antonio Fox

Great when you need to connect wires much smaller than 18-20. I have a feeling they are designed more for 22-26 gauge wire. The photos show the regular (red and gray) couplers I've used in the past and they are rated/advertised for 20-22 gauge wire. I think the description for them is wrong because I found black and red, but their description is for the 24-26 caliber. The photos show both side by side. Small for this rating. Other photos show them connecting the internal wires of RCA cables with heads cut off. The last photo shows the gauge of wire that can be connected. I had to use a transparent inner cinch wire because the black one was too thick (without having to force it).
