Double Roller

A quick learner from Heath, Texas says:
Product Code: 81-004
Air Control Roller single wheel assembly replacement. I have 3 sliding glass doors that are custom made 4'x8' and are very heavy. I would like to replace with a double wheel assembly. Can you recommend a replacement.

Thank you for your patience.

It seems as though the 81-095 Adjustable Tandem Roller could work on your door, however you will have to adjust the screw holes.

The screw that goes in the corner of the door holding the door frame together is a #12 on the 81-004; whereas the 81-095 has a 10-32 screw hole.

For the top screw, the 81-004 has a 10-32. The 81-095 has an un-tapped screw hole (it is not threaded), so you will have to tap it to a 10-32 thread.
