I have a cabin, circa 1976ish. My patio slider doors need roller assembly
replacements. They are a single roller assembly. The stamp on the roller
is.

Product of
Del Mar Eng Co
Long Beach Cal
Pat 3 670 357 (as best as I can tell)

The roller has a hook tab above the adjustment screw. The size is
approximately

1 3/8 in high
1/2 in wide
Body (outside hard single piece) 2 in length Attached hook tab 5/8 in

Appreciate any help you can provide to locate replacement rollers.

Thanks for your help
Respectfully,
Don

Thanks for posting, Don. It's tough to say. You mention your roller is 1/2" wide. Does that include the bumps on the side? If not, I'm wondering if you could use something like our 81-254. We also have the 81-148. Carefully look over the measurements we have for these rollers and let me know what you think.
