Heating Register Grates/Grills.
This is for the 5 (restored as bought) shown in the last image. Sold individually.
11.5 wide by 9.5 high with screw holes 9.5 inches apart. They have patent dates from 1900 to 1917. I believe the back panel would have originally been painted a very dark gray. Attaching screws are not included. They are in working condition.
See below for the sixth, larger one.
