My new house (been here two months) has a broken garage door window.
It's a Clopay door and there are metal pieces around the windows, and I
can't figure out how to remove them so I can get the broken window out,
and then replace it. I'm not talking about the insert, just the four
pieces that, I think, hold the window in place. Anyone know how to do
this? (No help at the Clopay web site.) Thanks for any help.
