patio door rollers & handles

A quick learner from Massachusetts says:
I need six replacement rollers and two handle sets for 1970 alumn. patio doors.

Sliding Patio Glass Exterior Aluminum Door
Heavy Duty - 1975 +/- Vintage - Purchased in Boston
I can't find any manufacturer's numbers or logos. It seems to be the same aluminum door as used on 1970's Deck Houses.

I need six replacement heavy-duty wheels with assembly. If double wheels will fit I'm sure they would work better for these heavy doors.

Slots (3/4" w x 7-1/8" h) for handles extend through both sides of the aluminum frame. I need two sets of heavy duty handles with lock mechanism.

We really need to see the roller assembly removed from the patio door. My guess is that you need the 81-004 roller, but you will need to compare the 81-004 to your original roller to be sure.

Can you send us pictures of your existing handle? Again, this is just a guess but possibly our 82-002 handle will work.

Hi Dave,
Thanks for your efforts. The original 1970's handle is long gone and various replacement handles have been adapted and used over the years. The slot in the frame is 7 1/8" high x 3/4" wide. The original handle had a retangular base that rested on and exactly covered this slot on both sides of the jamb.
The original rollers are currently needed to keep the sliding door in use and are difficult to photograph within their slot. Can you recognize the door from the photo and dimensions? These alumn. doors were very common in the Boston area in the 1970's and were used in 100's of prefab post and beam "Deck Houses" in nearby suburbs.

Jim, I do not recognize the door from the photos submitted.

Identifying the correct roller and handle will be extremely difficult without seeing photos of the original hardware.
