Question: Why can't this be used to go down instead of up? (With a short piece of straight into an elbow and more straights between the floor joists.)
Document: This item worked out well in our laundry remodel project. Makes a nice safe exit for our dryer - no bends to trap lint. Working out well and we are happy with the purchase. It was a fairly easy install - helps that hubby has construction experience - but I think most could manage this if you plan ahead. New construction would be easiest - but we used it in our remodel and it worked out well.
I installed for a 3rd floor dryer in a 2x6 wall.Installation want well.Pro's:Ease of installation.keeps pipe as round as possible.Helps hide pipe.Very rigid.Con's:No external trim(when you drywall over it you must be precise to keep a good joint(I caulked around edge to give a clean look).I will definitely buy again when I need to install another dryer.
we have a really narrow laundry room and anything i can do to get a few more inches of walking room was required. i don't know what to really say about it other than it makes a nicer hole in the wall than a lot of the other alternatives. it went in easy other than trying to deform the round-ish duct through the hole in the top that's slightly ovular.
Makes for an easy install and a being able to drywall up to it and paint it will make for a clean finished product
Functional and attractive. Would highly recommend  any home or remodel be framed with 2x6 behind the dryer to accommodate this box.
