(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

Recommended Product:

This wall cap was the only one available in 8 inch so I didn't have any choice however, it is well constructed. I have two minor complaints. There is no spring to keep it from flapping in the wind nor is there any rubber or foam to decrease the noise when it flaps.
