Inspect Patio Door
• Cosmetic damage.
• Correct product (size, color, grid pattern, handing, glazing, energy-

environmental conditions to exceed the patio door’s performance rating,
do not install the patio door. Contact your dealer or distributor for
recommendations.

should be the same. Maximum allowable deviation from square is
1/8" for doors less than 20 square feet and 1/4" for doors over 20
squarefeet.

allowable deviation is 1/8".
