EZ-Path 44 Series User manual

DESCRIPTION
The EZ-Path Modular Floor Grid System is designed to
facilitate the installation of multiple high-volume EZ-Path
Series 44 or Series 44+ pathways through oors. The rugged,
galvanized steel grid frame assembles quickly and easily and is
bolted over pre-formed openings in concrete oors.
Pathways in banks of four, form modules that easily install
through slots provided in the Grid. Grid sizes are available
to accommodate one (1) , two (2), or four (4) modules. All
grid sizes may be purchased as complete kits including
pathway modules (Fig 1). Multi-slot grids may be purchased
with blank restop ller panels (Fig 2) allowing modules to
be purchased and installed at a later date as needed.
Components: See Table A below.
NOTE: Anchor fasteners are required to secure grid frame
to oor and must be purchased separately. 3/16” x 1-1/4”
concrete screws are recommended. See Table A for the
number of fasteners required for the model chosen.
Floor grids (EZG444, EZG844 & EZG1644) include restop
ller panels to seal slots. Pathway module(s) (EZD444MB
or EZD444MBS) must be purchased separately.

PREPARATION
Orientation: Grids are designed to be installed with slots running parallel to cable pathway or support systems
such as vertical cable trays or racks (Fig 3).
Floor Opening: The EZ-Path Modular Floor Grid System installs into preformed, rectangular openings through
concrete oors. Opening must be properly sized and positioned. Dimensions vary according to the model selected
and are shown in Table B. Mounting of the grid frame requires an additional 2-1/2” of clear unobstructed space
beyond the periphery of the opening on all sides. Where standing water or ooding is a concern, it is recommended
that the grid frame be mounted to raised curbs formed into the concrete (Fig 4).
INSTALLATION
Assemble Grid Frame: Assemble grid frame by installing 1/4-20 x 1/2” bolts and nuts through anges at mitered
corners (Fig 5).
Mark and Drill Anchor Holes: Mark lines parallel to and an 1-1/4” from the periphery of the opening on all sides.
Place assembled grid over opening so that these lines appear under anchor holes in frame on all four sides.
Mark anchor holes and trace reference marks around the four outside corners of the grid frame (Figs 6 & 7).
Remove frame and drill holes for anchors.

Install Grid Frame: Place gasket on concrete (Fig 8). Replace assembled grid frame back over opening using
corner reference marks to reposition (Fig 9). Using concrete screw, probe through gasket to locate drilled holes.
Install fastener loosely. Continue installing fasteners. When nished, tighten all fasteners securely.

PATHWAY MODULE INSTALLATION
Assembling Pathway Modules: Pathway Module (EZD444MB or EZD444MBS) includes four (4) Series 44 or
Series 44+ EZ-Path Pathways along with right and left hanger brackets with nuts and bolts. Hook and eye attachment
is used to join all pathways into a single bank. Install hanger brackets on both ends of the pathway bank (Fig 10).
Insert Pathway Module (Fig. 11) through grid slot and suspend by placing hanger brackets on side rails. Install
and loosely tighten bolts and nuts (1/4 -20 x 1/2” provided). Install all pathway modules at this time using same
procedure.
NOTE: For single slot grid frame (EZDG444 or EZDG444S) it is necessary to loosen the mitered frame corner
bolts to allow pathway module to be inserted. After inserting module, install and tighten hanger bracket bolts
completely and then re-tighten bolts in frame corners.
Install Spacer Bar Assembly: In multi-slot grid frames, a spacer bar is used to separate pathway slots. After all
pathway modules are in place, install spacer bar(s) (Fig 12) by aligning with notches in side rails located between
pathway modules. Press down until top of spacer bar is ush with side rails.
Place spacer strap gasket in place over spacer bar. Install spacer strap over gasketed spacer bar, pressing strap
down tightly against gasket. Install clamping bolts at each end and tighten to clamp spacer bar in place. Tighten
pathway module bracket bolts (1/4 -20 x 1-1/2” provided).
Installing Firestop Filler Panels: Panels are used to seal any unused slots. If spacer bar(s) has been previously
installed, remove spacer strap and gasket. Place panel over slot with sheet metal side facing up (Fig 13). Align
edges of panel with frame rails and position to half-overlap spacer bar.
Holding panel securely in place with edges aligned, install panel clips (provided) at panel ends by pressing over
lip of panel and frame ange (Fig 14). Drive clip on completely. Install clip at opposite end. Use two panel clips to
secure long panel edge to grid frame. Replace spacer bar gasket and spacer bar strap (Fig 15) to secure panel
edges where they overlap spacer bar. Reinstall and tighten spacer bar clamping bolts (Fig 16).

ADDING PATHWAY MODULES
Additional cable capacity can be gained by installing Pathway Modules
(EZD444MB or EZD444MBS) through unused slots in multi-slot grids.
To add module, remove Firestop Filler Panel by removing panel clips as
well as spacer bar clamping bolts and panel strap. Remove spacer bar.
Install module (Fig 17) and reinstall spacer bar per instructions above.
INSTALLING OR PULLING CABLES
A resilient liner provides an adjustable seal within the pathway device.
Liner must be protected from damage while adding or removing cables.
Wrap cable ends with a suitable low friction tape before inserting
into the pathway. Where cable lubricants are used, low solids, water-
based products are recommended. This device is designed to be fully
functional at all cable loadings from completely empty to visually lled,
and cables should easily slide through the pathway using minimal effort.
IF RESISTANCE IS ENCOUNTERED, DO NOT FORCE CABLES
OR CABLE BUNDLES THROUGH THE PATHWAY. DAMAGE MAY
RESULT. Upper curved liner may be depressed when inserting cables,
if necessary, using a at, smooth implement and then removing it after
cables are installed. The rectangular shape of the loading area coupled
with gentle pressure exerted by resilient liners will naturally distribute the
cables at a relatively uniform height across the width of the device. The
use of a cable dressing/combing instrument to straighten and organize
cables may help to maximize usable space within the pathway device.
SUPPORTING CABLES
Allow slack where cables ow through pathways by providing support for
cables above and below the oor. Cable support system should orient
cables so that the ow is vertical through the center of the pathways.
