The first Cutler Mail Chute was installed back in 1884 in a building in Rochester, NY. Who knows how many of these are still in active use. I read that in Manhattan and the Bronx alone, there are well over 900 still in operation. Although, as a matter of fire safety, they have been banned in new construction since 1997. Which makes good sense. I suppose. I just love that there was an entire industry devoted to designing, manufacturing and installing these things. And, if you live in a city, you have doubtless seen, or perhaps even used, one of these. I can’t quite describe the thrill of seeing my little envelope hurtling downward into the box on the ground floor!
