Tandem metal patio door rollers

Question

Hi,
We have a heavy glass patio door that is hard to open and close. We think we need to replace the rollers.
Attached are some pictures of the rollers.

Markings on the roller "Del Mar Eng'rg co. Long beach, Cal. Pat pending"

Do you have a replacement roller for this?
Thanks
Bill

Your roller could be an older version of our 81-018. Check to see if the 5-3/4" mounting hole spacing match yours, along with the 1-3/16" height and the 1/2" width. If those all match up then you may just be able to get the 81-018 to work in your door.
