CREATING THE OPENING

Gypsum Board Walls (Square Openings):

1. Locate suitable area of the wall to penetrate making sure that there are no studs, wires, pipes or
other obstructions located within wall.
2. Mark a square or rectangular opening as dimensioned in Table A. Make sure opening is square and
plumb. The inside opening of the mounting plates can be used as a template (See Fig. 1).
3. Using a keyhole saw, cut wall board (See Fig. 2). Cutting to the outside of the line will produce a
slightly over-sized opening. Mark and cut opposite side of the wall, exercising care to align both
openings. Insert pathway and check for fit. Remove pathway.
4. Install device per instructions below.

Concrete or Masonry Walls (Square or Round Openings):

1. Cut or form a square or rectangular opening or core drill a round opening per dimensions listed in Table A.

INSTALLING PATHWAY USING WALL PLATES

Prior to Pulling Cables
Device is installed through wall and attached using wall plates
to sandwich the wall. No mechanical attachment to wall itself
is required.
1. If necessary, pre-install required set screws in mounting plates
using Allen wrench (provided). NOTE: When installing a single
wall plate and pathway, two set screws positioned and tightened
at 90 degrees to each other in both plates will adequately hold
device (See Fig. 3). Multiple devices in a ganged installation
using double (Cat No. EZP233W) or triple mounting plates
(EZP333W) require EVERY set screw to be installed.
2. Install a mounting plate around pathway making sure that set screw flanges are facing towards the
end of the device. NOTE: Position plate so that the word TOP stamped on the plate aligns with the
lid of the pathway. Use gauge marks located on lid of pathway to adjust plate to thickness of wall
(See Fig. 4). This will center pathway within the wall. When properly adjusted, tighten set screws to
lock plate onto pathway.
3. Place one of two provided gaskets around opposite end of pathway and carefully slide it back to fit
snugly against back side (wall side) of plate.
4. Insert pathway device through wall (with TOP facing upwards) using previously installed mounting plate
and gasket as a stop (See Fig. 5).
5. Moving to the opposite side of the wall, install remaining gasket around pathway and slide toward wall.
6. Install remaining mounting plate around pathway (TOP up) and slide it toward wall surface. While
pulling pathway toward you, push wall plate and gasket tightly to wall and tighten set screws. Check
device for excessive play. If device appears to be loose or can easily be moved, readjust mounting
plates as necessary to tighten device firmly against wall.

GENERAL - READ COMPLETELY BEFORE INSTALLING

This product allows for several optional installation methods. Available
methods for walls are shown here. The pathway device consists of an
enclosed heavy gauge galvanized steel channel with a detachable lid.
Depending on the type ordered, mounting plates and gaskets are either
included or may be ordered separately. Mounting plates are designed to
accommodate single, double, or triple device installations. Component
requirements will vary according to the method of installation chosen. See
Table B for additional information.
NOTE: WALL INSTALLATIONS REQUIRE THIS DEVICE TO BE
INSTALLED WITH THE TOP (LID) FACING UPWARD. The lid may
be identified by the BARRIER GAUGE stamping. WALL PLATES ARE
ASYMMETRICAL and are marked with the word TOP.
