For larger decks measuring deeper than 16 feet, the ZipUP UnderDeck Seam Trim provides the opportunity to create a complete underdeck drainage system without any additional designing required. By creating a cap at the end of the installed Main Rails and Panels, the Seam Trim piece allows for another section to be installed quickly and easily. Similar to the ZipUP Wall Trim, Seam Trims have channels on both sides in order to connect to two sections of ZipUP UnderDeck securely. Gain the outdoor living room you've always wanted with the beautiful, finished look of ZipUP UnderDeck.

This item is only needed if the deck depth exceeds 16 feet. Measure the width of the deck and divide that number (in feet) by 12. Round up to the nearest whole number to determine the number of pieces of Seam Trim needed. For decks between 28 and 42 feet in depth, you will need twice as many pieces as calculated in the previous step.
