The TW-19 is a half porch designed to be used on Natureline obround and crescent entrance inserts. It can also be used on natural gourds and Supergourds. These porches are attached to the insert by using sheet metal screws from the inside of the insert. DAP Latex Brilliant White Caulk should be applied where the porch and insert meet to cover any crevice and keep the birds from getting toenails caught. The cost of the TW-19 is $3.00 each plus S&H.
