Rigid Galvanized Duct (4-inch)

The default run we specify, and the only thing we will conceal inside a wall or ceiling. Smooth-wall galvanized in 4-inch nominal, joints crimped so they run with the airflow rather than against it, sealed with foil tape instead of screws. That last detail is the one most installers get wrong: a screw tip inside the duct is a lint hook, and once it starts collecting you get a blockage at a point nobody can reach without opening drywall.

More from the Duct aisle

Rigid Aluminum Duct (4-inch)

Same smooth-wall requirement as galvanized, lighter to work with, and the one we reach for on reroutes through finished space where the run has to be handled a lot before it is fastened. It meets the same code rules; the choice between the two is usually about the install, not the performance.

On the aisleQuote

Adjustable Metal Elbow

Every bend costs you length. Code counts a 90-degree bend as five feet of your allowance and a 45 as two and a half, so on a long run the difference between two elbows and four is the difference between a duct that clears and a duct that never will. We use adjustable elbows to hold the angle we actually need instead of forcing the run to fit stock fittings.

On the aisleQuote

Recessed Dryer Vent Box

A box let into the wall cavity so the elbow and transition sit inside the wall instead of behind the machine. It buys back four to six inches of depth, which is usually the difference between a laundry closet door that shuts and one that does not. It also stops the crushed-hose problem, where pushing the dryer back kinks the transition and the run silently loses most of its airflow.
