A sprinkler has a hollow outer case and a riser vertically reciprocable within the outer case through an upper end thereof. A nozzle is mounted at an upper end of the riser. A body cap fits over the upper end of the outer case and retains the riser. The body cap has a plurality of circumferentially spaced vertical ribs that connect a reduced diameter upper portion of the body cap with an enlarged lower portion of the body cap. An elastomeric cover extends over at least the reduced diameter upper portion of the body cap and at least a portion of the ribs.
