An adjustable hinge assembly is provided for use on a ventilator apparatus, wherein the ventilator apparatus includes a curb, a removable curb cap covering the curb and presenting side and rear edges, and a ventilator supported on the curb cap. The assembly includes a pair of laterally spaced curb cap support plates that each include a first arm adapted to be secured to the curb cap and extending along one of the side edges of the cap, and a second arm adapted to be secured to the curb cap and extending along the rear edge of the cap. The assembly also includes a back plate connected to and between the support plates along the rear edge of the cap, and a pair of laterally spaced curb plates adapted to be secured to the curb. The curb plates support the curb cap support plates, and define a pivot axis about which the curb cap support plates pivot between a first position in which the cap covers the curb, and a second position in which the cap is raised from the curb. At least one bracket is also provided with the assembly, and secures the back plate to the ventilator to support the ventilator during pivoting movement of the cap. The assembly is adjustable so that a single hinge assembly construction can be used universally with various sizes of ventilators.
