wheels for OLD patio door

A home owner from Kearny Arizona says:
We have 40+ year old sliding glass doors. The wheels are SHOT, we would like to purchase TWENTY replacement wheels, and put about SIX in the three-foot glass door, and up to TEN rollers under a very heavy 4-foot glass door. The new wheels need to fit into the slide-space, and not need to be drilled into the BASE of the DOOR because that might shatter the GLASS.

See attached phone image. Can we find a type of steel wheel that we can jury-rig into our older doors? I created an account so you should be able to find my info somewhere...

I re-measured my old patio door. It is THIN, only 3/4 inch full width, so the roller needs to be like 9/16-inch TOTAL WIDTH.

Plus, I'm thinking I can screw TWO new roller assemblies together, so they work, but don't need to be screwed into the DOOR frame.

Thanks for posting, Gerry! Please take a look at our 81-246 Roller Assembly. Do you think this might work for you? Please let me know!

This is absolutely AMAZING! Yes, I do believe that the 81-246 Roller Assembly WILL DO THE TRICK - but I need to ask if there is a way to put some kind of set screw into EACH HOLE of the 81-246 Roller Assembly, that will push UP against the BOTTOM FRAME of the door, and hold the WHEEL at the correct clearance to operate?? It does not look like the 81-246 Roller Assembly has threaded holes? If it DOES have threaded holes, what size machine screw would I use? Can you provide TWO of these machine screws for EACH of the wheels I purchase? I REALLY APPRECIATE your suggestion! THANKS!

Unfortunately, this roller does not take a machine screw. Judging by the installation holes, it only takes a regular sheet metal screw.

As for adjusting the roller, you should be able to use basic washers--which can be purchased at any local hardware store--to get the correct adjustment you need.

This will probably work for me, so I will order up a dozen, and see if they can be adapted THANKS A BUNCH for helping me save this old doors. Here is a photo of the VIEW I have from my living room, through these old 4-foot wide glass sliding doors. ALL the new double-insulated glass doors has THREE FOOT glass, so it would add one more POST and detract from my view. so if I can KEEP these old doors a bit longer, it's a nice thing to have!

I really hope these rollers work for you, Gerry.

That is a definitely quite the view! I'm not afraid to say it-- I'm jealous.
