The DuoDeck under deck bracket represents a simple way to convert unused space under your deck into living or storage space. The brackets mount to the bottom of your deck joists. Graduated maks on each bracket make it simple to create a pitch which drains water away and leaves you with new usable space. The bracket is quick and easy to install and works with 2 in. x 2 in. lumber and Palruf corrugated roofing panels to create a ceiling under your deck.
