INSPECT ROUGH OPENING
REMOVE PACKAGING
Remove shipping materials such as corner covers, shipping blocks or
pads. Remove any temporary handles just prior to installation into the
rough opening.
INSPECT PATIO DOOR
• Cosmetic damage
• Product squareness (diagonal measurements must be within 1/4"
difference)
• Verify the width and
height of the patio
door are each
1/2"- 3/4" smaller
than the rough
opening width/
height. Mulled
units should be 3/4"
smaller.
• Verify the rough
opening is square.
The (A) and (B)
measurements
should be the same.
Maximum allowable
deviation from square
is 1/4".
• Correct product (size, color, grid pattern, handing, glazing, energy-
efficiency requirements, etc.)
• For side-by-side mulled units, a drip cap that extends the length of the
frame plus 1/8" overhang on each end is required.
If any of the above conditions represent a concern, or if you expect
environmental conditions to exceed the patio door's performance
rating, do not install the patio door. Contact your dealer or distributor
for recommendations.
