Instructions

By the end of this step your build should look like this

1 - Slide cross bars onto side bars

Align the cross bars made in the previous step with the longer side bars as shown in the images.
Slide the cross bars halfway up the inside of the side bars, making the shape shown in the above image.

2 - Tighten the L-brackets so they are flush with the side bars

With the cross bars pushed fully onto the side bars tighten the L-bracket screw as shown in the image to make the cross bar flush with each side bar.
Do NOT tighten the L-bracket screws in the side bar tracks, the cross bars should be able to slide up and down between the side bars.
Using just a bit makes this easier due to the limited space. A hex key will also work.

3 - Push the silicone alignment inserts into the cross bar track

Push the silicone inserts into the cross bar tracks as shown in the images, with the larger insert in the centre, separating the T-nuts.
This is to align the T-nuts for attaching to a VESA mount plate through the panel backplate.
