Are they like this Bob?
If so, the Sewells are twin and a fraction of the price. If you put a dab of anti ox in the cap, then screw it onto the wire, you are set for life. I used mine for 10awg no problems.
Matt, use some type of anti ox compound. Never get the 20milli ohms issue later.
Zakry like that! That's a great tip, 4 years and 9 months later than I needed, but thanks just the same, Trevor. And it really won't help me in the future, either, as I bought extras before Radio Shack went OOB around here.
Thankfully, Charles thinks they're cooler as Monsters. Thanks for backing me up, CV!
