Will the 10-058 roller replacement fit My Track Size?

The rollers on the top of my shower seem to be about 21mm in diameter. The track opening measures 23.74mm, so if your rollers are 15/16 in, they seem like they might be too large to fit inside the track. The bottom track opening seems to be about 20.96mm. Will the roller wheels fit into the bottom track?

I have attached photos of the rollers on our shower. Is it best to order a set of 4 when replacing these?

I'm afraid I do not have any specific specs on what tracks our 10-058 can fit in, but based on your pictures I think these are our best option. You have an older version of the 10-058, which is no longer made. If our roller cannot fit in your track, then I don't think anything else on the market will. I personally think they will work fine.
