Builders Best 10151 Close Elbow: Optimize Airflow Efficiency in Tight Spaces Review

They work great. Our laundry room is planned so that the dryers are in the room first. I've always preferred the washing machine to be the first appliance and the dryer to the right. in the wall. Worked perfectly and the pivot function on these elbows is good too. Really makes for a clean/tidy install.

No holes in fastener for easy attachment to drywall, no flange wide enough to drill your own holes unless the hole in the wall is large enough to slip elbows in. The larger hole and flange cannot reach the drywall to attach the flange. EDIT: I had to put something up to hold it against the wall so it wouldn't blow off the wall and blow out all the hot air and lint that got in through the screen inside the house.

This is not so. This is aluminium. This means it's thinner and thinner than steel tubing (as any plumber knows). In some installations this may not matter. But if it's the part sticking out of the wall that the dryer connects to, it can easily expand and is useless for a good connection. In such a case, a short piece of steel tubing should be added to the open side to create a strong "nipple" for the connection.
