Have you ever tried to fit something through a doorway, just to find that the door itself was in the way? Just ask anyone who has ever been confined to a wheelchair at some point in time, they will tell you that most doorways are too narrow to begin with.
One solution is to remove the door altogether, but in modern homes today, the only rooms that have a door are bedrooms and bathrooms. A little privacy please?
A great solution to this problem are Swing Away Hinges (also called Offset Hinges). These hinges swing the door completely out and away from the opening, adding almost 2" of clearance.
The last time I checked, a pair of Swing-Away Hinges were selling for around $20 on Amazon.com. Now isn't that cheaper than a reciprocating saw?
