How to Adjust Glass Door Hinges When Door not Close Fully

“We had a glass door installed with self-closing hinges about 3 1/2 years ago. The door at first banged so hard on closing it vibrated the entire front desk area of our dental clinic. With adjustments it now no longer closes fully and often gets stuck in the open position. Can you assist me in a solution”

A dental clinic reached out to us about their self-closing glass door. When first installed, the door slammed so hard and rattled the entire front desk. Now, after several adjustments, it often sticks open and fails to close fully.

Commercial glass doors depend heavily on precise hinge tension and alignment. If your door isn’t closing as it should, here’s how to adjust your glass door hinges for smoother, safer performance.
