I am building and hanging a new wooden double gate. How do I construct and/or balance the gate so that when I open it completely, which is at 90 degrees, it will stay open but also when I close it, it stays closed?
Yes, I might put a self-locking latch so that when it is closed, it automatically catches and stays closed. Is there another way to do this? I plan to use a dead-bolt type lock, and would prefer that you not have to unlatch it to open the gate when not locked.
This is an double gate, where one gate door is 40" wide the other is only 20". I'd like both sides to behave the same, staying open and closed. I am not overly concerned about very windy days, where the wind might defeat a balanced system.
I could use gravity to make the gate stay closed by itself. The trick is, I think, that I also want the gate door to stay open too, when I open it.
EDIT: Closer! I find that there are weld-on hinges for chain-link fences that do this, and that they make "Rising Hinges" or "Lift Off Hinges" that do half the job. Many of these are designed to use gravity to automatically close a door but all of them seem to sell only as wholesale items.
