A microwave range hood requires a shelf or cabinet above it for proper installation. A mounting bracket supports the weight of the unit from the back, while bolts support the unit via the shelf above it.
The weight of a microwave range hood warrants care to ensure that sufficient support is present for safe use of the appliance. The rear mounting plate installs flush to the wall behind the unit and connects to the wall studs using multiple screws. A lip at the lower edge of the mounting plate mates to a corresponding lip on the back of the appliance to provide a pivot point during the installation. Bolts screw into the top of the microwave through holes drilled into the supporting shelf.
