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 at the right.
To correct problem
Go to Item 5.
3. CHECK OPENING ACTION OF GLASS PANELS
A. Lift up adjacent glass panels at the same time
and note the following:
B. Do the corners of the glass maintain
an even gap throughout the travel of the
panels? And do the corners touch or
overlap at any point?
To correct problem
Go to items 4 & 5.
4. STRATEGIES FOR CORRECTING UNEVEN GAP AND OPENING OVERLAP PROBLEMS
VERTICALLY adjust the hinge(s) to even the gap
A. 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.
B. Adjust outside hinges (Center hinge station-
ary) 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.
