The Robe Runner™ fitment here is a single part, a 60mm plastic timber door floor guide that also replaces Tudor™ guides. A wardrobe door hangs from rollers at the top and is only steered at the floor, so the guide is the piece that takes the abuse: the plastic wears oval, snaps at the fixing, or is kicked out of the floor altogether, and the door then swings at the bottom and rubs the jamb. Replacing the guide often settles a robe door that has started to flap without touching the top track at all. Measure before ordering, since 60mm is the identifying dimension and floor guides of this pattern are made in several sizes. Check the thickness of the door bottom too, and how the old guide was fixed down, as that decides whether this one will sit flush.
