1991 Acorn Dorwal replacent parts

A quick learner says:
We need a replacement handle and rollers for our Acorn Dorwal 8' patio door. Our condo was built in 1991 and this is the original door. It's too cold to take the door off right now to show you the rollers but I'm sending pics of the handle. A security sticker on the jamb says Series 1200. I don't know if that is helpful.

Hello,

Take a look and compare the specifications of the 82-055 and keyed 82-055K Acorn handle sets to yours.

Unfortunately, we can't determine the rollers that you need with them still installed but feel free to get back to us with photos of your part once the weather warms up a bit and we can go from there. We will also need you to write-out the housing width, thickness, and wheel diameter to compare to our inventory. Thank you.
