5STEP FIVE
Trim the four sheet metal tunnel pieces so that they are
1/4 “ shorter than the thickness of the wall. Use a jigsaw,
nibblers, or a bandsaw. (A jigsaw blade is provided.)
Be careful to trim the correct side. Do not trim the side
of the tunnel pieces that attach to the flap frame.
8STEP EIGHT
Slide the larger tunnel pieces onto the finger tabs
on the top and bottom (smaller) tunnel pieces.
Bend the finger tabs down as shown below.
10 STEP TEN
Place the Interior Frame, with the tunnel attached, into
the opening in the wall from the inside of the building.
Place the Exterior Frame into the tunnel.
13 STEP THIRTEEN
Apply a bead of silicone sealant (provided) along the inside of the
tunnel where it mates with the frames and along the tunnel seams.
Be careful to seal all gaps and seams to minimize
the chance of water damage to the wall.
6STEP SIX
Bend the frame attachment tabs on the two smaller tunnel
pieces 90 degrees upward along the perforations.
Be careful to bend the tabs in the right direction. The tabs will
break if bent more than once. Some tunnel pieces have a joggle
9STEP NINE
Tip: A screwdriver
handle works well for
bending the finger tabs.
Tip: For especially
heavy dogs, you
may wish to sup-
port the bottom of
the tunnel with a
piece of wood.
11 STEP ELEVEN
Loosely insert the 4-inch screw into the head of the barrel nut.
The screw can now be used to help guide the threaded rod through
the interior and exterior frame. The 4-inch screw will create a
(offset). Bend these tabs as shown with arrow. Tunnel pieces
that do not have a joggle can be bent in either direction.
WARNING:
The tabs may
break if bent
more than
once.
7 STEP SEVEN
Remove the two screws at the top of the Interior Frame (the
frame that has a locking cover). Attach one of the smaller tunnel
pieces to the top of the Interior Flap Frame using the two screws.
Repeat this using the other
small tunnel piece along the
bottom of the flap frame.
Cut the four threaded rods so that they are 3/4 “
longer than the thickness of the wall.
Tip: Thread a nut (provided) onto
the threaded rod before cutting.
When finished cutting, removing the
nut will straighten the cut threads.
Cut 3/4 “ longer than the thickness of the wall.
Screw the four threaded rods into the
four barrel nuts to form long screws.

12 STEP TWELVE
Insert the threaded rods with the barrel nuts into the four holes in
the Interior Frame (the frame that has a locking cover), and
screw the threaded rods into the Exterior Frame finger tight.
Check that the pet door is level and tighten the threaded
rods until the weather stripping compresses fully.
Be careful not to overtighten
Use handle for each
14 STEP FOURTEEN
Tap the hole covers into the Interior and Exterior Frames.
Tip: The wooden handle of a hammer, or similar non-
metal tool, works well for tapping in the hole plugs.
