4’ (122cm) (1220mm) 18mm Sliding Door Track Black. Top track and bottom track as pictured, Other lengths available Collection is welcome from us in Preston Any questions just ask These Double Tracks have a wide centre leg in order to space the boards, doors or panels that run within them. This means that cupboard or wardrobe doors, which typically have protruding fittings from handles or locks, can run unobstructed in the channels. With the deeper Top track and shallower Bottom track, these Double Tracks can be fitted before installing the doors or panels. Note that there are no metal fittings for these Double Tracks, such as wheels or internal guides - they rely on the doors sliding on the low friction PVC.
