81-166S vs 81-166?

Question

Hi,

The 81-166 and 81-166S appear to be the same product, but the measurements listed on each site are off. The 81-166S is listed at a height of 1 and 1/4 in and the 81-166 is listed as 1 and 5/16 in. Is the 81-166S listed incorrectly?

I need the 1 and 5/16 in height version in steel rollers, so would the 81-166S work?

Thanks for reaching out to us. The given dimensions for these products is accurate. The housing style is similar but it is a little different between the two of them.

You can try the 81-166S if you think you can get the 1-1/4" style to work in your door. Otherwise, you could always get the 81-166 and 81-266 wheel kit (sold separately). You can then install a new steel wheel on the 1-5/16" style.
