A home owner from Mt Royal, NJ says:
I have a replacement mortise lock for an exisitng american craftsman 5500 patio door. The previous owner broke the interior know off and threw it away. Can you tell me what the orginal know looked like and do you carry it? Thank you Jim

The American craftsman 5500 series normally uses the #82-218 mortise lock. Go to the SWISCO website just to make sure the dimensions line up.
A home owner from New Jersey says:
Are all American Craftsman Series 5500 patio doors 1-3/8 wide?

I believe they are 1-3/8" thick, but that's no guarantee. You should measure your door just to be sure.
