Abstract: A handle assembly includes a pair of mounting brackets and a handle pivotally coupled to the mounting brackets. Each mounting bracket has a U-shaped mounting member and a hook shaped clamping plate coupled to the U-shaped mounting member through threaded tension bolts. The mounting bracket also has a pair of mounting flanges with handle holes through which extends inwardly turned ends of the handle.

Abstract: A hinge assembly includes a pair of lower mounting brackets, at least two upper hinge leaves, and an axle pivotally coupling the upper hinge leaves to the lower mounting brackets. Each lower mounting bracket has a vertically oval-shaped axle hole. Each upper hinge leaf includes a U-shaped mounting member and a hook shaped clamping plate coupled to the U-shaped mounting member through threaded tension bolts. The upper hinge leaf also has a pair of axle holes. The axle extends through the elongated axle holes of the lower mounting bracket vertical flange and through the axle holes of the U-shaped member.

Abstract: A hinge assembly includes a pair of lower mounting brackets, at least two upper hinge leaves, a pair of side brackets coupled to the sidewalls of the ventilation fan lid, each side bracket having at least one third axle hole therethrough, an axle pivotally coupling the upper hinge leaves to the lower mounting brackets. Each lower mounting bracket has a vertically oval-shaped axle hole. Each upper hinge leaf includes a U-shaped mounting member and a hook shaped clamping plate coupled to the U-shaped mounting member through threaded tension bolts. The upper hinge leaf also has a pair of axle holes. The axle extends through the elongated axle holes of the lower mounting bracket vertical flange and through the axle holes of the U-shaped member.

Abstract: A grease catcher includes lower mounting brackets that are mounted to the exposed end of an exhaust fan duct. A tubular body riser is coupled to the lower mounting brackets that has vertical walls that terminate at a top edge. The lid includes a central portion and downwardly extending sidewalls. The lid is spaced from the top edge of the body riser. An exterior housing is coupled to the body riser. The exterior housing has a floor and exterior walls extending upwardly from the floor. The exterior walls are spaced from the lid. The exterior housing is positioned concentrically about the body riser and the lid sidewalls are positioned concentrically about the body riser and concentrically within the tubular exterior housing to form an undulating airflow channel A removable grease absorber is positioned upon the exterior housing floor.
