Two wall mounts are needed to mount a rod between two parallel walls.
The wall mount adds 6-7mm to the rod length on each side.

1. Attach a wall mount to each wall with a 4.5mm screw (suitable length).
   The rod support structure must be facing downwards.
2. Cut the rod to the appropriate length.
3. Slide a cover part onto the rod one each side
4. Place rod on the fixed wall mounts
5. Screw the covers onto the wall mount parts.

Hint: 
Apply some silicone grease on the thread, so it can be easily be assembled and disassembled.
(Without grease, the thred tends to wind on and off somewhat “sticky”.)
