Convert any Comstock 9x11 trap into a flush mount trap with this adapter. These trap extensions guide animals directly from a den opening into a trap. When a standard Comstock Series 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 adapters extend the length of the trap past the open door, allowing the trap to be mounted flush against a wall or any other structure. This accessory measures 6L x 9W x 11H and is constructed from 1" x 1" wire mesh.
