⬢Place the xl-dock-cable-router on the bottom metal sheet below the aluminum extrusion.
⬢There is a protruding screw from the xl-dock-cable-router. Attach the screw to the first screw hole on the long metal profile. Through the hole in the rear metal sheet, check if the cable holder is lined up with the hole.
⬢Push the 2.5 mm Allen key all the way through the hole in the rear metal sheet until you reach the middle screw in the xl-dock-cable-router and tighten the screw.
The dock is a press fit, so the screw needs to be tightened very hard.
Attach all the remaining docks using the same procedure
