Good Morning,

Thank you for your patience. I am currently in the process of researching possible replacement rollers. I will post an update as soon as I have more information to share.

This particular style roller with the T-tab design has been discontinued by Del Mar. We are still working on possible substitutes for you.

I'm also looking for the same rollers, par # 3,670,357 with the #1 on top.I don't believe 81-254 or 81-255 will fit unless the back is open ? Can't tell from your photo's.

Do you have a replacement wheel that would work
The closest we found was your product code 81-148
- but we can't tell if it is an exact match..

So what did the original homeowner from CA end up using? Did 81-254, 81-255 or 81-148 actually work in place of the Del Mar Eng Pat. #3,670,357?
Home Owner from Sacramento, CA
Today I was ecstatic when the 81-148 rollers fit my 1976 roller doors (wheels Del Mar engineering, Long Beach, CA, Pat 3,670,357)! I lived with a bum wheel on one of the doors for 10 years now, and ordered 4 of the wheels 81-148, and although the dimensions varied by 1/8 to 1/16, and the tab was different than my original wheels, they fit great. The wheel diameter was important though, I think, although it is adjustable, and there was plenty of wiggle room above the sliding doors in the top chase. Minor adjustment needed on leading wheel when installing - I needed to bend tab up to fit into slot of door. But worked like a charm, along with the Slider Slicker with teflon - doors run super smoothly now. Adjustable wheel position not necessary for me, but adds that flexibility.
Thank you!
Patrick
