Bought them in a bucket at a garage sale, but wonder if I can use them

What is this stuff?

Those are latches for a double swinging door without center post.
They mount into the edge of the door and the metal "tounges"
flip to move rods up and down into ceiling and floor either
latching or unlatching the "fixed" side of a double door.
The warehouse in the building where I work has 3 sets of
doors with those types on latch on one side.
The other thing is a push down rubber foot to hold said door open.
It mounts low on the door surface.
