US 2008/0302883 A1 · WORKING SPACE ENCLOSURE FOR UNDERGROUND SPRINKLER HEADS

Abstract

A protective sprinkler head housing for allowing access to sprinkler heads and shafts for maintenance and repair. More particularly, the present invention relates to a device which allows for, and encloses, a working space around underground sprinkler heads. The device is placed around a sprinkler shaft in the ground and the plant material is placed on its outside. The top of the sprinkler head sits above the device. When the sprinkler needs to be accessed, the top of the device can be removed and an open interior space remains where a user can place his/her hands and/or tools to repair or replace a sprinkler head. This invention may be installed when the underground sprinkler system itself is first installed or alternatively may be installed at each sprinkler head as needed.
