"Good quality piece and fits together well with the other pieces in the range. Only installed last weekend and so reliability is only 4, but no reason to believe it won't be reliable. Used in a DIY project to vent hot air from tumble dryer in a basement to above ground level."
"Purchased this along with a right angle and ducting. Got me out of a real fix having moved the tumble dryer into a different location and found the round ducting meant it wouldn't fit. Well made and accurate joints meant it was a dream to install."
