MaxSeal Flap Connector Thumbscrews
MaxSeal thumbscrews have a black know that is knurled for easy grip. This thumbscrew also has a 9/64" Allen wrench hex head so that you can tighten or loosen the thumbscrews. We recommend that you periodically check the thumbscrews with the included Allen wrench for tightness to ensure that your pet door operates optimally.
Note: The flap connector thumbscrews are not included with replacement flap purchases. You should use the existing thumbscrews from your original flap when replacing a flap. Additional thumbscrews are available if needed for purchase.
