3. Strategies for correcting Glass Bounce and opening overlap problems
Adjust hinges FRONT - BACK.
A.
As this diagram indicates, pulling the middle hinge further back, pulls the inside edges closer to the
surface or edge which the glass rests upon. And pushing the middle hinge to the front, pushes the inside
edges further away from the surface or edge which the glass rests upon. (See Vertical Adjustment of
Glass)
B. Adjust outside hinges (Center hinge stationary)
As this diagram indicates, pulling the outside hinge further back, pulls the outside edge closer to the
surface or edge which the glass rests upon. And pushing the middle hinge to the front, pushes the inside
edges further away from the surface or edge which the glass rests upon.
Which hinge(s) should I adjust fi rst?
In most cases the center hinge is the fi rst candidate, but if the arm/minicam is at its maximum or minimum
position, then obviously the outer hinges must be used. (See Vertical Adjustment of Glass)
Vertical Adjustment of Glass
A. Adjust outside hinges (Center hinge stationary)
This diagram indicates that raising the outside hinges widens the gap at the bottom; whereas, lowering the outside
hinges will draw the bottom edges closer together.
Which hinge(s) should I adjust fi rst?
In most cases the center hinge is the fi rst candidate, but if it cannot be adjusted because, either the adjustment screw
is "maxed" out or no additional shims can be added or removed, then obviously the outer hinges must be adjusted.
Installation (Cont'd)
Adjust center Hinge (Outer hinges stationary).
