Because of restricted space i would like to convert the round dryer pipe outlet to a rectangular pipe and then back to round as it exits the wall. The rectangular section seems to be be a much smaller cross sectional area, so is it suitable for my tumble dryer. Thank you
Do you make a Tee similar to above adapter?
Thank you for your question. Unfortunately only equal tees are available in the round and rectangular ducting. The codes for these items are QS254 for the round tee and QS169 for the rectangular ducting. If I can help any further please do not hesitate to contact me
