Abstract
A sprinkler head includes a nozzle, a frame and a rigid mechanical fusible link assembly positioned between the frame and a closure plug or cap. An annular, normally concave spring is disposed between the cap and the nozzle. The spring creates a force which throws the link assembly clear of the head upon actuation.
