Bottom Roller Assembly for Charmac Doors as per Label

Nylon roller appears to be 1 1/4", but could have been larger originally. There are no other markings on the doors or the rollers other than the above label. Examining your pictures, the 1 1/4" and 1 1/2" look as if they may be interchangeable. Is that an accurate assessment? I noticed that the 1 1/4" only listed King as a manufacturer while the 1 1/2" lists Charmac in addition to several others.

Thanks for posting. The roller in the 23-043 is adjustable, so you should be able to accommodate the 1/4" difference in height. That said, carefully compare the dimensions of both the 23-043 and the 23-198 with your old roller to see if one matches better than the other--note that the 23-198 has an overall height of 1-5/32", while the 23-043 as a height of 1-1/4". See what you think.
