Not intuitive to install the first time, but it eventually made sense and the subsequent installs were very easy. Very heavy duty and handles a solid core door with ease. NOTE: The thickness of this hinge WILL leave a gap at the top of your door. If you're using it for a door that will swing in, you can place the top moulding slightly lower, to mask the gap. If yours is a swing-out door, or you otherwise don't want a gap between the top of the door and the bottom edge of the top frame, you'll want to choose a different type of hinge.. Thad. Fairfax, VA.
