ASSEMBLY AND INSTALLATION INSTRUCTIONS

for Custom Wood & Fiberglass Exterior Folding Door Systems (JII101)

• The exterior face of the rough opening must be in a single plane (E)

with less than 1/8" twist from corner to corner.

• If using an ADA sill, a

recess will need to be

available in the rough

opening sill for the

channel to sit in and

allow the sill legs to

sit flat on the rough

opening.

• If using a U-Channel

sill, Fashion the recess

using the dimensions

shown. Position the

head track in place of

final installation and

use a plumb bob to

find the exact location

of the sill recess.

Hang the plumb bob

from the center of

the roller track. The

center of the recess

will be 23/32"from the

plumb line towards the

interior.

3. Measure the width

of the frame and
add 9/16".

Note!

The most

important criteria for

a successful job are

a square opening, a

properly engineered

header (evaluated and

structurally designed

to carry the combined

weight of all the panels)

and a clean track.
• We recommended

that the head be

installed with a slight

bow upward (typically

1/8" at the center

of the opening) to

allow for the door’s

weight pulling down.

The frame should be

checked for square and

twist.

• Verify the width and height of the door are each 1/2"- 3/4" smaller

than the rough opening width/height.

• Verify the rough opening is square. The (A) and (B) measurements

should be the same. Maximum allowable deviation from square is 1/4".

• Verify the rough opening is level and plumb (C). The maximum

allowable deviation is 1/8".

• The rough opening sill must not be crowned or sagged (D) and be

level or sloped (positive slope) to the exterior.

Verify Square, Level, and Plumb

REMOVE PACKAGING

Remove shipping materials such as corner covers, shipping blocks
or pads.

INSPECT DOOR

• Cosmetic damage

REMOVE PACKAGING AND INSPECT DOOR

• Correct product (size, color, grid pattern, handing, glazing, energy-

efficiency requirements, etc.)

If any of the above conditions represent a concern, or if you expect
environmental conditions to exceed the door's performance rating,
do not install the door. Contact your dealer or distributor for
recommendations.

INSTALL SILL PAN

A sill pan can be ordered with some products (check with a salesperson),
found in building supply stores or online (search “sill pan”), or fabricated
on the job site (details below) with the proper tools and materials. Note!
Sill pans are not designed to be used with ADA or U-Channel type sills.
Weather-proofing these types of sills is the responsibility of the installer.
An adequate overhang and a positive slope are recommend with these
sill types. If installing into a stud-framed wall and using a drip cap, at
each corner of the head, slit building wrap 6" at 45° and tape up. Skip
to Section 6, “INSTALL DOOR.”
