1/4" Mono Big Fatty Phone Plug
1/4" Mono Big Fatty Phone Plug is rated 4.4286 out of 5 by 7.
Rated 5 out of 5 by from Boating ApplicationThese plugs works nicely with the larger gauge wire that I use for hooking up my boat electronics to my custom made power strips.

Rated 4 out of 5 by from Good redesignI'm glad you had this plug redesigned because I had nearly 100 percent failure with the Big Fattys from my previous orders. The problem was that the assembly got loose and the tip solder tab would rotate around enough to short out to ground. Thankfully my PA can tolerate a shorted output. I'm sure you heard about this or discovered it yourselves. So far the new ones are holding up nicely.

Rated 4 out of 5 by from What more do you want?I have used both brands of these big barreled connectors and this is the one I prefer. The weak spot is generally where the 1/4 inch barrel egresses from the main body. The other brand uses a more brittle material to make it stiffer, but then if it is over stressed, it breaks. This one is softer so it bends and keeps on working. Stll not a perfect solution, but the better choice of the two available.

Rated 5 out of 5 by from quailty plug for the moneythis is the cheapest big barrel plug you can get anywhere. also it is the best for use with 12awg speaker wire, sounds gggggggggrrrrrrrrreat.

Rated 4 out of 5 by from Good not HEAVY dutyI consider this acceptable, and priced below most other acceptable products. I think I saved a dollar on the plug vs. the switchcraft, which is the standard by which I judge other products. If you are looking for the "last plug you'll ever buy" this one may do it. I expect it to last a very long time and stand up to moderate wear. These are not as heavy duty as the switchcraft products. It is machined well, but has a different alloy - it's lighter metal than switchcraft, and it doesnt' take solder as quickly.If you want to save a few bucks on a big plug, this will be OK. If you can get the switchcraft plugs for near the same price, it's a no-brainer.

1/4" Mono Big Fatty Phone Plug

Will this connector accomodate a 12 guage speaker cable? It must have a very large connector to work for me.

Asked by: Mike673
As long as the jacket of the cable is less than 11.2mm or 0.44" in diameter this will work. I cannot say based specifically on gauge since the jacketing is different on every cable.
