PLEXIGLASS JOINING

Note: All split cases are set, leveled and joined
together in the factory to ensure proper alignment
and tight joints between the cases. To obtain
equally tight joints in the field, it is critical to use
the GE 1200 silicone supplied to seal case joints.
Only silicone allows case joints to pull up tight!
Do not use Permagum! It will cause large gaps
at case joints and prevent plexiglass from joining.
