Every Mooney or Piper Pilot will appreciate the quality workmanship in every one of these storm window hinge/latch kits. Professional construction means they work smoothly, and they fit standard factory window holes with no modifications.
Piper no longer produces the trim handle, and an estimated 10% of 31,000 Pipers on the registry which utilize their handles. The OEM handles is a very weak link in the entire door assembly. Everything downstream of the handle is pretty secure. Therefore, they have improved the handle and have the requisite FAA STC and PMA for the production of them.
