We searched the internet for appropriate garage door handles, but couldn't find anything suitable that wasn't really expensive. We decided to show the iron-workers who built the deck railing a picture of what we wanted and they were able to duplicate the handles. It only cost $50 for the pair.
Here are the handles.
They needed to be painted black along with the hasp lock.
I finished painting with a roller the following day.
I then installed the lock and handles.
Here is a shot of the whole house the doors blend well into the concrete.
I had enough paint left to use on the surface of the worktable.
