Abstract
Abstract A wire guard for a pendent or upright sprinkler head, the guard being adapted for installation with one hand. Each of a number of depending wire stirrups lies in a plane with its ends fastened to a spreadable circumferential wire base loop. The base loop is discontinuous with a fastening and sprinkler head engaging means spanning the discontinuity. The base loop is resilient in a region opposite the discontinuity to permit the guard to be installed upon a sprinkler head.
