There are several techniques (tools) that can be used
to cut a hole in stainless steel. For the purpose of this
Guide, instruction included will describe the steps
required to cut the portal holes with a Nibbler using a
11/16" cutting head.
The cutting head will have to be locked into place,
perpendicular to the handle of the Nibbler. "Free"
and straight cutting positions could cause clearance
issues due to the location of the hole and its proximity
to the back and bottom panels of the cage. See
FIGURE 2.12
STEP 1:
Insert the cutting head into the hole and locate a starting point to begin the cut.
See FIGURE 2.13
FIGURE 2.13 - Start Cut
FIGURE 2.14 - Rotate Nibbler
STOP cutting, realign at any point during the cut if the cutting head strays from the hole
guide line. Mis-cuts can damage the cage and affect the seal of the Portal.
STEP 2:
Rotate the Nibbler as it cuts the steel, following the hole guide line.
See FIGURE 2.13 to 2.16

STEP 3:
Bend, file any edge surfaces protruding from the panel
wall that could affect the seal. See F
IGURE 2.17
STEP 4:
Remove metal shavings and clean the cage of debris.
