can product number 81-259 be used to replace prime line d-1761? the prine line product is has a stell roller and is 1/2" shorter in length. all other measurements are the same.

The Prime Line D1761 is Discontinued, It looks like the 81-259 is only longer in length. I do not believe the length will be a problem as long as the other dimensions line up to your original; the wheel should just sit a little deeper in the bottom of the door rail.
