Sprinkler assembly with cap and cover
A sprinkler assembly includes a body defining an inlet, an outlet, and a fluid passage extending along a longitudinal axis between the inlet and the outlet. A guide pin aperture is defined by at least one of the body or a bushing coupled to the body. The sprinkler assembly further includes a deflector slidably coupled to the body. The deflector includes a deflector body coupled to a guide pin. The guide pin includes a shaft portion extending through the guide pin aperture and a shoulder that is wider than the shaft portion and configured to engage at least one of the body or the bushing to limit movement of the deflector body away from the body.
