For sale is a Zurn Wall Hydrant Box Only (no hydrant, just the box)P1300-Box, which includes the two screws to hold the hydrant (purchase separately) into the box.  I am not sure if this is brass or bronze, please see images. It is about 6-1/2" square and 2" deep.

The finish on the face/door of this box is not perfect (please see the images) but is perfectly functional.  Also, it looks like the lower pin for the door hinge has been replaced.  You could easily find another split pin at a hardware store to make it "look" original. There is no key with this box, but the latch works as it should and will function properly with any available 3/8" key.

What is in the images in what you will receive, no hydrant is included
