I'm sorry to say that we don't have a replacement for this door roller. The only thing we have that comes close is our 81-248, but the back screw tab on ours is vertical, not horizontal. If this can work then you'd have to bend that back first. Even then, I can't be sure it will suffice.

It's not for a door it's for an aluminum window

Thanks for confirming. I'm sorry for missing that detail in your first post; I guess I was too focused on the roller itself. To be honest though, the fact that this is for a window only confirms that we have nothing like this. That must be some huge window to use a roller in this style. We just don't have anything like this.

Thank You for trying. Its actually a small drive up window . Just alot of use.
