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.
Parts List
• Plastic rod, 1 in. (25 mm) long,
3
/
16
in. (5 mm)
diameter
• Acrylic Solvent Cement (IPS Weldon #40 or
comparable, mixing instructions below)
• Masking tape and duct tape (not supplied)
Instructions
1. Prepare front plexiglass for cement applica-
tion by placing masking tape not more than
1
/
16
in. (6 mm) from the seam, on both sides,
front and back. Tape is to protect plexiglass
from cement spill over. Scarring will occur if
cement touches clear plexiglass.
2. Separate front plexiglass pieces enough to
apply a bead of #40 cement down one edge
inside of seam and plastic rod area.
3. Apply cement with applicator to one or both
surfaces.
Join immediately.
4. Realign front plexiglass and push together
tightly. Insert the plastic rod until flush with
top of plexiglass.
5. Apply just enough pressure to remove any air
bubbles. Do not squeeze joint so hard as to
force cement out of the joint—a dry joint may
result.
6. Apply tape (2 in. duct tape recommended)
across face of seam to secure plexiglass from
shifting while cement dries.
7. Allow approximately 4 hours to dry at 70°F.
Weldon #40 (2-part) Cement Mixing Instructions
1. Bring Parts A and B to room temperature
before mixing.
2. Add Part A to Part B. Quantities have been
premeasured at the factory.
3. Stir slowly and evenly to avoid air bubbles.
Mix for 1-3 minutes.
