Galvanized metal, 6 feet long, 2 inches wide, has 2 tracks so it can be used to hang 2 rollable panels. Wheels available at Home Depot. It can use wheels up to 7/8 inch diameter.
For example, if you take a 3 foot wide piece of latice and you attach little wheels at the top, you can make a 36 inch sliding "door" to desguise unsightly in the garden or anywhere else. Used. $5 (First and second pic's.)
Aluminum, Alum-Slide sliding door track (from Macklanburg-Duncan Co). I have 2 brand new packages. One for 6 foot wide doors, the other for 8 feet wide ones. Each package contains 2 tracks, one for above and the other for below the door.
Both sets contain tracks with these spec's: 1 13/16 inches total width, each of the 2 channels being 7/8" wide. It has predrilled holes every 14 inches to fasten it to the top or bottom of an opening, depending on how it is being used. Each package contains 2 different pieces, the only difference between them being the height of the sides. One track has 5/8 inch sides, the other 3/8 inch sides. 8 foot one $25; 6 foot one $20
