Upgrade your dryer vent system with this Square-to-Round Dryer Vent Transition, designed to eliminate one of the most common lint-trap problems found in attic dryer vent risers.
In many homes, a rectangular sheet metal riser terminates in the attic, but the vent continues using a round pipe installed into the side of the riser. This sharp, awkward connection creates a major airflow disruption that catches lint, restricts performance, and increases clogging over time.
This transition piece installs directly at the top of the square riser, converting the outlet to a smooth, centered round connection. The result is a straight-through airflow path that allows a new round vent pipe to attach cleanly—without the extreme side-entry angle that causes buildup.
