I am looking to replace old sliding door rollers (two of them). They are metal (brass color) and have a '123' stamped on the housing. No idea what they are beyond that or what type of door it is.

Approximate measurements are 2.5 inch long, by 1 and 1/8 inch high and 1/2 or 5/8 inch wide The wheel itself appears to be 1 1/4 inch diameter and has about 1/4 inch groove

This roller looks like a good match for our 81-032B at first glance, but our dimensions differ slightly from yours. Look them over just to be sure.

Thanks for the reply. It would seem as though the width is too much here. The one that we pulled out was less than 3/4 inch wide (it was just a hair over a half inch wide).

Is there anything narrower?

You need to measure the "bumps" on the sides of your roller. The body of the 81-032B is 9/16" wide, but the bumps extend that to 13/16", which is what you're trying to reach.
