1. An enclosure for a wall hydrant comprising:
a housing having a round configuration and having means for containing the wall hydrant;
a cover pivotally attached to the housing wherein the cover can move from a closed position to an open position;
a slot within the cover wherein a portion of the cover can slide about the slot into the housing when the cover is in the open position; and
wherein the cover has a domed portion to accommodate larger hydrants.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
