On an exterior door hinge there is a small 1/4 inch tab hook punched out of the metal on the door side of the hinge that fits into a 1/4 inch hole on the jamb side when in the closed position. Always being one wanting to learn, I have no knowledge of this configuration and was wondering if any had insight as to the purpose of this design?

Rez,
No promises, but when I first saw that I assumed (oops<g>) that it was a simple security-type feature so that if the pins were pulled from the hinges the door couldn't be knocked out of the opening.
Again, no inside corporate knowledge on my part...just a guess. I'd be interested in knowing the real function, too.
Sounds presentable but the door opens in with the pins inside. Maybe more safety than security?Half of good living is staying out of bad situations.
Most exterior doors are inswing, but not all. The tab is for security when a door is mounted outswing.
Yeah, its for security alright. You can make your own security hinge by leaving two opposing screws out and driving a 16d finish nail into the jamb side leaving a half inch sticking out. When the door is closed this 1/2" of nail will prevent the pins from being pulled and the door removed.
