This trap is constructed of an aluminum angle main frame and is held afloat with high density styrofoam on all four sides. There are two aluminum flippers attached to stainless hinges that dump the turtles in the trap. The flippers automatically reset themselves. 31 in. long by 22 in. wide by 22 in. deep.
