This is a really nice vent to replace the old flapper type that was installed on my house when built new.  I only have to remove the cover and the inner cap when cleaning out the dryer vent pipe with the cleaning kit purchased "Woodeze 5GA-RLE202 LintEater Rotary Dryer Vent Cleaning" which I try and use on a bi-annual schedule.
