3. How to install rail tracks
Mark the correct width on the slotted track to avoid damaging the slots. Insert wooden slats or polystyrene scraps while you cut the track with the hacksaw.
If there are no holes already drilled, drill the first hole five centimeters from the edge, then drill every forty to fifty centimeters on alternate sides of the two slots. Hold the strip flush inside the recess to mark the drill holes. If you are working alone, two or three strips of double-sided tape will make the job easier.
Mark the fixing points. Remove the slotted track and drill. Insert the wall plugs and screw the strip in place. Mark the width of the bottom rail and cut to fit.
