Product review (4 stars): A must have for a non-vented installation of the AP130 or RP130 exhaust fan.
This product was used in conjunction with the Broan RP130SS exhaust hood to replace an over the range microwave oven

Quality materials are used in the construction of this hood. My installation under a recessed cabinet means I had to use shims to make up the 1/2 in. recession. To ensure it would carry the weight o\f the fan I glued and screwed 2 pieces of 1x2 with countersunk #10 wood screws. To hang the hood (Broan RP130SS), I replaced the 4 screws provided with 4 #8x1in. stainless wood screws to give a stronger support by screwing into the cabinet base not just the shims.

I would have given this product 5 stars except for the fact I had to drill a hole in the top of the unit through which the power cord would pass.  Since the only application of this product would be to install a non-vented exhaust fan one can assume the power cord would need to pass through the top or back of the unit.  A "knockout" plug would saved me the need to do that.
