Searching for large sliding glass dooor rollers

A quick learner says:

Can you please help me find these rollers ?

They are on some very heavy impact doors

I took the door out and wrote down measurments

I think the rollers are 1-3/4" not 1-1/16"

I could not find either

as well as the 6-3/4" hole to hole measurment

Thank You

Thomas

Hello,

We'd be happy to look into this for you but we would need to see photos of your original roller to compare to our inventory since the details needed to confirm a replacement can not be adequately shown in a drawing. Thank you!

Thanks for getting back to us. Your photos resemble the 81-184 but the hole spacing of our part is 6-7/8". Take a look and compare the specifications shown below to your part.
