TW-8 4" tunnel with crescent adapter screwed on, single width exterior porch, interior cling rod $6.50
The TW-8 is like the TW-4 4" tunnel, but the crescent adapter plate is screwed on. The purpose for attaching the adapter plate with screws is to provide interchangeability among holes. If you suffer SREH anxiety, or prefer trying to start a new colony with round holes, then you can use the TW-16 or a TW-16A round hole adapter plate until your birds have built nests or laid their eggs, then by removing 2 screws, switch the entrance to a crescent. Then, apply a small amount of latex caulk to waterproof the area where the adapter meets the tunnel. The TW-8 is for larger natural gourds, or Supergourds. The TW-8 sells for $6.50 plus S&H.
