Then I realized: This is because someone else installed my doors. Oh yeah, that's right.
Now, if I had installed my own doors--and I've done plenty in the past--this would be a different story. Not only that, even the most flawlessly opening/closing doors will eventually stick and scrape. That's a law of nature.
As The Original Adjustable Door Hinge documentation reminds us, doors can go janky for many different reasons: over-painting, humidity, foundation movement, new flooring installation, and poor craftsmanship.
And no, planing and belt-sanding your door is not an option. Ever tried it?
These appear to be normal hinges, but with a crucial twist: a bolt running vertically, with the head on top and nut on bottom. The hinge sleeves have room to allow for a little extra play.
You can adjust these hinges as far as 1/8" to the sides and 1/4" inch top-to-bottom. If that doesn't sound like much, believe me--relative to door installation, these measurements are like miles.
These adjustable door hinges definitely fall into the category of Why-Aren't-All-Hinges-Like-This?
