ABSTRACT:
A pet door comprises a hinged flap mounted within a fixed frame and pivotable to allow passage therethrough in both directions. A locking mechanism is provided comprising a slide with two projections thereon which, in different lateral positions of the slide, are aligned with corresponding projections or cut-outs on the flap to allow or prevent pivoting of the flap in one or both directions. The locking mechanism can thus be set as desired to allow free access in both directions, to allow access in one direction only (in or out as desired) or to prevent any opening of the flap.
