replacement of door flaps
Great product lasted 20 years of use by four dogs. When the time came to replace the door flaps viewing the video was certainly beneficial, though no where as easy as depicted when it came to removing old screws, several of which simply striped. Without the use of my Dremel and cutting discs to either cut the screws or create a good slot in the head for a flat blade screw driver, I would have been in serious trouble. Anyway, after an hour or so of sweating and swearing, all is well. I hope for another 10 or 15 years of service from this door.
