Underdeck Systems Installation Guide

STEP 6: PANEL INSTALLATION

1. Begin to install, or hang your under deck panels. You will be

interlocking these panels into place against the previous panel.

2. Each panel is screwed using 1 ¼” galvanized screws into the carriage

system, making sure that the end of the panel is properly positioned

in the gutter. You can make the needed adjustments with your

screws to insure the panel rests on the gutter.

3. To repeat the next panel, make sure to push the panel into place so it

interlocks with the previous panel. Repeat this process until finished.

NOTE: Be sure to open up the ends of the panel channel, as they

make have become pinched during the preparation stage.

STEP 7: TRIM OUT THE PERIMETER OF YOUR NEW SYSTEM

1. Using the provided trim coil, you will now finish the look of your

system with trim around the system.

2. Begin with your ledger board and install the trim with a 90® bend

that will slide behind your panel and zip screw into your panels.

3. The remaining trim for the sides of your system will be bent using a

“stair step” bend to account for your outside deck board, as well as

your slope of panels.

STEP 8: DOWNSPOUTPLACEMENT AND DRAINS

1. At the pre-determined spot, drill a hole in the gutter to install the

downspout. Hold your elbow or downspout over the hole, and mark

around the outside to make a template. Be careful to center the

downspout or elbow on the bottom of the gutter. With your snips,

cut an “X” to the corners of the downspout template you previously

marked and bend the 4 triangles down to create a flange to screw the

elbow to.

2. Install downspout and elbows with provided straps. Always use the

color matched zip screws for all exposed surfaces. Make sure you

attach each piece of the drainage system with caulking to prevent

leaks.

STEP 9: FINISH AND ENJOY

1. Finish your new Raintight Underdeck System with the enclosed trim

package that will cover all the exposed wood beneath the deck. You

are now ready to enjoy that new out door space, even if its raining
