For this step you'll need the following:

1PC- Part 9: Exterior Exit Panel

1PC- Part 10: Interior Exit Panel

2PC-3D Printed Flange Nuts (Part 31) & 2PC- TF Screws

Laser cut "Drumstick Tool" included with the faceplate panel set.

Sandwich the Interior and Exit panels together as shown so that the finished side (MDF version only) is facing outward on both sides. The interior panel will be taller than the exterior. This is normal. When the screw holes are lined up the top edge of both panels should be flush as shown.

Press two TF screws through the holes in both exit panels as shown. Fasten the flange nuts with the flange side towards the interior exit panel as shown. Hold the flange nuts in place with the included "Drumstick tool" and tighten the screws. Repeat the process for both sides.

Fit the assembly into the rectangular notches of the sidepanels as shown. Press the two sidepanels tightly against the base/back assembly. You may now tighten the bottom two TF screws on the side you left loose so it all stays together.
