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.
