De Mar Engineering rollers

Question

I ordered 4 replacement rollers (81-148) for my slider door after reading on line that other customers used them for the same type of door, though they don't have the same features and thus won't work. I have a De Mar Eng Co, Long Beach ,CA door with two Pat. 3.60.357 stamped rollers. I read the your SWISSCo 81-148 rollers were interchangeable but aren't. Our original rollers have two screws: one that adjusts the height of the door and the other to secure the rollers to the door. Also our rollers have grooves that side into a track on the bottom of the door. A third feature we need are locking posts on the roller part that pop into a hole on the door to again secure the rollers in place. What alternative rollers are there?

Would you be able to remove one of your rollers from the door and take a picture of it? Del Mar has used countless rollers over the years and across the country, so there's no way to know for sure what you have without seeing the original out of the door. Even if a customer has the same series door as you have now, there's no guarantee that you have the same roller hardware. Patio glass doors are more varied than that, I'm afraid. The only way to know is to compare the rollers themselves.
