How do I know if a product can be used for my application?

Local codes must always be followed. If you are not sure if you can use a specific product, we recommend you contact your local building department in your town. Rules vary not only state to state, they also vary town to town. We are not able to determine specific restrictions on all the products we sell. There are no restrictions preventing the shipment of any product to any area as many products are installed in a different location from where the item is shipped. Therefore we are not responsible for shipping a product which you may not be able to use. Always check your local code before ordering.
