I have been helping my neighbor replace a broken pane of glass in their
garage door. All the other doors I have done this to have had a
removable frame on the inside of the door, attached with screws, so
replacement is straightforward.

However, their door's window frames don't have a screwed-in frame. It
looks like the frame itself is a one piece extrusion and I can't figure
out for the life of me how to put in the new glass.

I looked for the manufacturer and all I could find was a small sticker
that had ADM on it - no address or anything. Google and other searches
did not turn up any company website.

Any ideas on how to insert the glass? Anyone heard of ADM or know how
to contact them?

Thanks - Jim
