Need bottom track and rollers
Hello,
I can't be sure without seeing how the part attaches to the door but I suspect you may have a part similar to the top roller guide shown in another customer's post here. If so, the 23-222C would be our best replacement option, which was recommended by Stanley to replace the old-style version of this guide. Take a look and see what you think.
As long as the rest of your hardware is still in good condition, you shouldn't need to replace the tracks or bottom guides. If you need any other parts, we'll need to see photos of those as well, since most closet hardware does not come as a kit.
Or should we replace top & bottom rollers and top & bottom tracks? Do you sell a kit, or is each part sold separately?
Your discontinued Stanley roller can most likely be replaced with the 23-041 Mirror Wardrobe Door Roller Assembly. You'll need to carefully review and compare the dimensions to confirm that it is the correct fit.
As long as your roller has a convex wheel, see the 48" long 23-240 track. As I mentioned, these closet parts are not available as a kit, so each part would need to be purchased separately.
