You'll need to decide how high and how close to the walls you want the cupboard tracks to go. Measure and mark these distances along the walls. Then use the spirit level and pencil to draw a straight line from one side of the wall to the other. A good idea is to leave 300mm at the top so you can store something above the cupboard.
Secure the horizontal track to the wall by screwing in 40mm timber screws at the points where you found the wall studs.
Click your vertical wall strip into the tracking nearest the wall corner and hang it down from the screws you've inserted. Use the spirit level to make sure the strip is hanging straight and mark a straight line with a pencil. Then secure the strip to the wall with the cordless drill and 40mm timber screws.
After securing the first vertical strip, place a track cover on the wardrobe track, which will act as a spacer. Place the second vertical strip onto the rack, next to the track cover and lock it into place. Use the spirit level to make sure it's straight. Secure the strip to the wall with 40mm timber screws. Repeat this until all of the strips are in place.
If you don't have a wall stud behind where you need to drill, drill a plastic toggle into the plasterboard first. Then you can drill the 40mm timber screw into the plastic toggle to hold the wall strip in place.
When installing the brackets for the shelving, work your way down from the top so you get the spacings that suit your needs. Clip the first bracket for the top shelf into the hanging vertical strip and then lock the plastic lever into place to secure. Then work across the horizontal tracks until all of the top shelf brackets are in place.
To hang clothes in your cupboard, you'll need to install a hanging rod. The hanging rod brackets slot into the bottom of each of the top shelf brackets. Adjust the length of the rod to match the length of the shelf. After putting end caps onto the rod, clip the rod securely into the brackets to hang clothing from it.
Now you can install as many shelves as you like at the height you want. Make sure you attach brackets into the wall strips, and then secure them by clipping them into place.
To build a sliding basket, start by making sure the arrow on the frame is pointing upwards. Use a drill to attach the brackets into the pre-drilled holes on both sides of the basket frame. Then clip the basket frame to the vertical strips. Put the basket into the frame and it's ready to use.
