SWISCO - The Replacement Hardware Authority

Miller California Sliding Glass Door

A handy person from New York says:
I have Miller California sliding glass doors to my patio. I am sure the wheels are in need of replacement. Is there one standard size for all their sliding glass doors? If not, what do I have to look at to determine which size I need?

Dave from SWISCO responded:
The only true way to determine which size is needed, is to actually remove your existing roller from your door, get your measurements, and match it up to our catalog. You can send us photos of your part if you get stuck and need us to take a look.
A quick learner says:
Please find attached a digital image of the existing tandem roller.
Can you help in isolating a good replacement?

It looks like SWISCO product code 81-149, Sliding Glass Door Roller. Compare the measurements from the product page on our site to your sample.
