Acorn Dorwal Sliding Glass Door Parts

Thank you for posting. It looks like you have a thermal Acorn door. This is something that Acorn made just before they went out of business.

Now, based on these pictures, it's very hard to determine what the roller is. The only way you can know for sure is to remove the door and take the rollers out. That said, it could be our 81-030. I cannot be sure without seeing yours removed, though. See the video below which shows how to remove and replace glass sliding door rollers. 

For the door lock, I recommend that you consider our 82-055. It may be a little different from yours, however. I'm hoping that the inside mechanism is still in the door frame, since the locking mechanism for our 82-055 is for the regular Acorn door. Maybe it just fell in there. When you replace the rollers, you will be removing the bottom rail of the sliding door. When you do that, you might find the locking mechanism down there, as well.

You can order all of these parts directly from our site.
