Thanks. All my bigger wrenches are in my box here at work. I'd like to take the right wrenches home to install these when they get here. I'm not particularly fond of using adjustable wrenches if I can help it.
If you've got two, that'll make it easier. Being LH/RH threads, you'll just need to crank on them simultaneously in the same direction. Opposing threads makes that very easy and is an advantage most don't think about.
