installing Grass euro hinges
I am trying to replace a Grass hinge on a cabinet door. I can remove the two screws from the mounting plate but the hinge is still as secure as ever.
On a new hinge there appears to be a nylon threaded bushing that the screws are secured in. What is the function of this bushing? How are these bushings anchored into the cabinet door?
How do I remove the old hinge from the cabinet door? Removing the two screws does not loosen the hinge.
Enclosed is two pictures of the hinge showing the bushings.
