The (4) hinged panels, fold down over the top, sides and rear of a 18" x 5" x 5" squirrel trap to form a solid walled "like" trap at much less cost.

They also help to keep the captured animal out of the sun or other inclement elements to prevent hypothermia. The covers give you the versatility of a solid walled or a mesh walled trap.
