The UL website states there are now three manufacturers producing the 'new' listed type raintight fittings - all three make them from 1/2 - 1 inch, with the larger sizes soon to follow (I hope )
I checked out the UL site and saw that now T&B/Steel City have a listing for raintight fittings. I noticed the instructions for the couplings call for a inch pound torque when installing.
