Optional Tunnel Fitting
If required, the optional tunnel should be fi tted at this stage. Use the
tunnel to bridge the gap between the external and internal frames to form
a short extension for your pet door.
Tunnel Template
Measure the thickest part (T) of your cut-
out. Note this measurement (Fig. 5).
Depending on the thickness of your door,
you may not need the tunnel template and
tunnel extension pieces or the tunnel
extension pieces may need to be trimmed
for your installation. Use the "Tunnel
Extension Pieces Cutting Guide" (Chart 1)
to determine this.

tunnel template and tunnel extension pieces.
No cutting of tunnel extension pieces is needed. Use
