The sill can be prepared using one of two methods: We recommend
SureSill™ Sloped Sill Pan™ available from SureSill at www.suresill.com,
building supply stores, and some manufacturing locations or fabricate a sill
pan on site. If installing a SureSill™ sill pan, follow SureSill™’s instructions
for installation and skip to section 4 “PREPARE BUCK“, or to section
5, “PREPARE STUD-FRAMED WALL“ as it applies to your situation. If
fabricating a sill pan on the job site, follow the instructions below.
JOBSITE FABRICATED SILL PAN
1. Cut a piece of sheet
material to the
length shown.
2. Lightly crease folding
lines 1/2" in from the
two short sides and
one long side.
3. Measure the width
of the frame and add
9/16".
4. Take this distance
from the back edge
and lightly crease a
folding line across
the sheet material.
5. For step-down
landings, cut 1/2" in
at this line on both
sides of the sheet
material.
6. For continuous slab,
cut across the folding
line.
• Verify the width and height
of the door frame 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".

• Cosmetic damage
7. Fold the three back sides
up to make a 3-sided
box, and, for step-down
landings, fold the front
flap down.
INSTALL SILL PAN
1. Set the sill pan in
the rough opening,
aligning the front
edge (for continuous
slab) or folded down
edge (for step down)
with the exterior of
the rough opening.
2. Mark a line across
the front and back of
the sill pan.
3. Apply three 3/8"
beads of sealant
between the lines.
4. Place the sill pan in
the rough opening.
Firmly press the sill
pan into the sealant
with a J-roller.
Sealant
• 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.
• 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). A 5 degree
sloped sill is recommended.
• The exterior face of the rough opening must be in a single plane (E)
with less than 1/8" twist from corner to corner.
