Was completing a WVC conversion today and something happened that I don't know whether it was the box or the colder weather. We finished the last two valves and were getting the jumbo box ready for final set by cutting out the ends to make it fit properly over the inlet and outlet lines. Partner was making the last cut when the corner of the Carson box split completely along the corner. This box came from Ewing as that is what is carried by them while our primary supplier sells a different brand. Partner had to run back to the shop to pick up another box which cut fine when he got it back. The Carson box seems to be harder and more "plastic" while the other seems a little thicker and denser with that "rubbery" effect. Am I imagining this or was the colder weather this morning playing tricks with us?
