Sliding Glass Door - Roller Replacement

A home owner from New Hampshire says:

Hello,

I am trying to verify the part number to replace the rollers for a sliding glass door. I have attached pictures of the part I need to replace. There are 2 single wheel rollers, one on each side of the slider. I am thinking its part 81-002, but not sure. I have attached some pictures of the part. There is an inscription inside the part with 68/30 (68 on top, 30 on bottom).

Thank you

Sally

Hi Sally. I agree! The 81-002 does look really close. You will have to compare the dimensions to confirm for sure. Let us know what you find.
