Multi-purpose adapters are used as trap extensions to guide animals directly from den openings into traps. They combine the features of directional nose cones and flush mount converters. Nose cones direct animals into traps from horizontal den openings, such as holes in the ground, or openings in the floor of a building. Flush mount converters direct animals from vertical den openings, such as holes in a wall or in a tree. Multi-purpose adapters do both.
