Rated 5 out of 5 by from Nice quality jackI needed to make up an adapter that I used to be able to buy, the close quarters inside the connector does make soldering a bit tricky, but the finished product looks good and work well

Rated 5 out of 5 by from Exactly what I was looking forI used several of these each paired with dual bananas for a couple sets of pro-gig amp-speaker cables, and the double solder lugs for the tip allowed me to use 12 gauge stranded. Had to get it quite hot to allow the solder to flow, but as long as you don't apply too much pressure the plastic won't melt. After the second assembly it was a breeze.

Is this a stereo image for this MONO plug?

By looking at the picture showing the connection terminals, this looks like a STEREO item (ground + 2 terminals) http://www.parts-express.com/pe/showdetl.cfm?partnumber=090-312 . I am not an expert, but if this image actually belongs to the MONO jack, what are the 2 small centered terminals for? How to connect them for MONO. I am making a speaker cable extension. I need a mono one. Thank you.

This jack has three solder tabs but is only mono.
