About This Product
"Please don't use a "vice-grip" or pliers or channel lock pliers to install your brand new $300 CarbonDoser regulator. The nut is make from brass and can be damaged by any thing other than the correct size wrench.
This wrench is made from nylon/plastic so it won't damage the nut. Also, it stays with the regulator so you'll never have to ask your kids or wife: where the heck is my wrench!
