Plastic Channels and Tracks
PVC is a low friction, smooth surfaced plastic that is suitable for sliding glass, ply, boards, plastic sheet and many other common materials. For some of the profiles there are raised runners within the bottom tracks that allow dust and any grit to sit beneath the glass or panel, leaving sliding uninhibited.
Both the single and double tracks are paired up in deep top and shallow bottom tracks, for the convenience of retrofitting and removing panels. See the video for more information.
