Flush Mount Converters are used as trap extensions to guide animals directly from an exit/entry hole into a trap.
When a trap is set with the door open, the door extends a few inches past the trap frame which prevents it from being flush mounted. However, flush mount converters extend the length of the trap out past the open door, allowing the trap to be mounted flush against a wall or any other structure with an animals den opening.
To use, place the flush mount adapter in position against a wall and over the animals den opening. Then bait and set your trap and slide it into the other end of the flush mount adapter.
