How do you install the BBQ-260-SV-1724?

The BBQ-260-SV-1724 door has a 2" deep back frame that (measures approximately 17 1/4"W x 24 1/4"H) on both sides that extends into the opening on your grill island. Screws are installed through pre-drilled holes on the back frame into your grill island. Please give us a call if we can help further. Thanks!!!
