Qty: Add to Cart Add to Wishlist

These tunnels come with the Conley 2 entrances and are made to be mounted onto wooden or aluminum houses.

The tunnel offers additional safety by increasing the compartment depth to keep nestlings at a further distance from predators.

To use the Troyer Collar drill a 3" hole into any type of martin house: wood, vinyl, aluminum with a flat surface.  Screw or rivet into place (screws and rivets NOT provided).  The  units are UV protected, made from polyethylene.

The Troyer Tunnel features a wing entrapment guard and wide porches with traction tread installed.  Trap compatible (TTT).
