The hinges are spec grade stainless steel, but without bearings. Rust-resistant, but low frequency. I drilled a set screw into each pin, for security. The door sags noticeably, but there is a "ramp" to raise the door as it closes.
I open the door a few times a year, to break it free if necessary. Once, the three-year-old neighbor girl saw the sign and read, "Exit!" The neighbor kids are fascinated by the window, especially when I open it and yell at them in their yard.
The neighbor kids own our front screened porch. It's sometimes a hair salon, and sometimes a dentist office. With the patient reclined in the anti-gravity chair, the "dentist" proclaims, "Let's see if you're ready for braces."
Our driveway, three cars wide at the garage, is their race course, for skates, bikes, and battery-powered kid-size cars.
Our front yard is a gymnasium in season, for cartwheels and other feats. After a few inches of snow, the yard was a bobsled course, with mother and oldest daughter pulling the youngest daughter and the youngest, a boy. (The second-in-line daughter was probably inside reading, or doing piano lessons.)
And they all enjoy the basement rec-room, with an array of Fisher-Price toys for the younger ones, and puzzles to challenge all of them. My son says that these kids are our surrogate grandkids.
