Abstract: A sprinkler head protection arrangement is provided having a first plate which is connected to a pipe providing fluid to flow through the plate, a sprinkler head mounted in the first plate to receive and control the fluid flow, and a second plate removably clamped to the first plate with a rigid cage mounted thereon to surround and protect the sprinkler head. The cage is formed from rigid links and rings which resist impact deformation. The second plate is secured to the first plate with minimal fasteners. An impact force absorbing spacer can be mounted between the plates. The sprinkler head can be further separated from impact forces by connecting to the first plate through a sleeve or bushing.

Abstract: A guard for a fire-suppression sprinkler head may be attached directly to a water supply pipe of the sprinkler head. A cage may be configured to surround the sprinkler head and a base plate may be configured for attachment to the pipe. The cage may be attached to the base plate.
