The storage system best suited to deal with a sloping ceiling is the Relax system
, by using Floor to Ceiling Stanchions
here is why:
Sloping Ceilings are at an angle that is not parallel to the floor, this represents a challenge to fix the Relax posts. There are two solutions for this: you can make a block out of soft-wood with a 90 degree angle and an opposite face that matches the angle of your ceiling and then attach this to the slope Or you can purchase some Angle Ceiling Blocks
to fix to your slope and to provide a surface parallel to the floor for the stanchions to be attached to.
The second challenge is the height, however, Our Relax stanchions can easily be cut down to size by removing the foot (taking out one screw) cutting the post to size and fixing the foot back into place.
You can then use shelves, hanging bars drawers etc available in the range as normal.
