Strategies for correcting glass bounce and opening overlap problems

before calling for service if something seems wrong, check the following:
1. inspect the gap between the glass panels
a.if pinched at the top: gap is more narrow at the top than at the bottom.
Correct UNEVEN GAP and opening overlap problems by Vertically adjusting the hinge(s) to even the gap Adjust
center hinge (Outer hinges stationary) As this diagram indicates, raising the middle hinge draws the bottom
edges closer together. Whereas lowering the hinge widens the gap. (See Vertical Adjustment on page 9)
b. if pinched at the bottom: gap is more narrow at the bottom than at the top.
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. (See
Vertical Adjustment on page 9).
Which hinge(s) should I adjust first?
In most cases the center hinge is the first 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
2. Check closing action of the glass panel
Test each panel by gently pushing it to close. Does the glass panel bounce or wobble as it closes?
A glass panel that does not close smoothly and neatly, most likely is misaligned with the front edge of the glass and
the surface or edge which it closes upon. Refer to diagram below.
