New door for spiral stairs

2013-01-27.StairDoor_0435A metal doorframe and self-closing wooden fire door has been added to the spiral stairs.  There is no doorknob at this writing.

Update: Although the door has veneer surfaces, it is a code-rated fire door as shown by an information plate on the hinge face and verified by Ken.  The interior of the door is a mineral substance, visible in the doorknob mounting hole.

Springs in the hinges swing the door shut with a loud bang, so watch out.
