Can I install an Austral Retractaway 40 clothesline on a wall other than brick?

Yes you can but you will just need to make sure the mounting holes at the back of the cabinet align with the structural supports in the wall. 

If not then a Post Kit is recommended with the clothesline and install it freestanding in front of the wall.
