Replaced factory original hinges on the double french doors leading to our patio. They had rusted due to our proximity to the ocean. Found these to be very well made, with excellent fit and finish. Fit exactly in the space that the old ones did. Screw pattern was slightly different from our original, but that didn't make installation anymore difficult, and probably made the new connection tighter. Comes with a set screw which locks the pin in place, but allows for pin removal when the door is open.
