Five embodiments of a sprinkler head protector provide an annular body defining a central hole and having a variety of differently designed spikes for retaining the body in place about a sprinkler head. A first version of the invention provides an annular body anchored by four large nails or spikes that may be driven into place by use of a hammer. A second version of the invention provides a one-piece unit including a body having four attached fastening spikes. A third version provides an annular body anchored by four spikes each having tapered top portions that insert into, and are frictionally engaged by, holes in the bottom of the annular body. A fourth version of the invention provides an annular body as in the first version, but provides four spikes which are attached to the body by fasteners such as screws. A fifth version of the invention provides an annular body 100 having four spikes which are threadedly attached to the body. In all of the above versions, a solid annular body may be used for extra strength, or to save costs, a semi-solid body having a lower surface combining web elements and partially enclosed hollow areas.
