Dryer Vent Adapter Rebuild

When we bought this house, it had its original clothes dryer, which was vented directly through the wall with a few inches of 3×10 inch square duct. Alas, contemporary dryers use 4 inch round hoses, so I conjured a round-to-square adapter from a length of air handler duct:

I’d used … wait for it … duct tape to hold the end caps on, because I knew I’d be taking it apart to clean out the fuzz every now & again. The most recent cleanout occurred when I noticed the end cap had eased its way out of the adapter, releasing warm fuzzy air behind the dryer.

The solution, which I should have done decades ago, holds the end caps in place with sheet metal screws:

Dryer Vent - screws installed

A pair of small clamps held everything in the proper location while I applied a suitable step drill and installed the screw:

Now the duct tape just seals the gaps, rather than holding against the minimal pressure in the box, and it should be all good until the next cleanout.

So simple I should’a done it decades ago. Right?
