Vintage 3 sliding door cabinet ... plastic runners

[wbmkk]

I have just been given a vintage long length sideboard, which has three sliding doors.

Each door (except middle one) has two wee white plastic 'sliders' which fit in the groove at the bottom of the doors, then the other edge, slides along the plastic double-slotted track runners fitted to the cabinet floor.

What are these called and does anybody know where I could buy some.

The middle door is loose, but for the sake of buying a couple of sliders I'll end up with a nice cabinet.

Many thanks !

Unlikely to get exactly the same but thick nylon washers could be used secured to base of doors.

Good idea

I actually thought about cutting two of them in half .. at least then I would have 6 runners
