Installation of Walkercell Distribution Raceway (WCR11/2, WCR2, or WCR3) to Junction Box:
At each Junction box that has an opening for Walkercell Raceway strike a baseline to correspond with the center
of the Walkercell Raceway distribution run. Each raceway has a piece mark number that must correspond with the
location shown on the installation drawings.
Position the first support bracket 6" [152mm] from the edge of the Junction box and a maximum of 5'-0" [1.5m]
on center thereafter as you proceed away from the junction box.
The raceway access opening of the junction box is provided with a support ledge and an adapter to couple the
raceway to the junction box. Adjust the adapter on the junction box so that the profile of the adapter rests on top
of the raceway.
Slide the raceway in along the brackets and onto the support ledge located on the Junction box. Adjust all brackets
vertically until the raceway is level.
Complete the coupling of the raceway to the junction box by securing the adapter and the set screws on each side
of the adapter.
Secure the brackets to the form with suitable fasteners.
Installation of Walkercell Raceway to Walkercell Raceway:
Place a Wiremold raceway support at the center of abutting sections and a maximum of 5'-0" [1.5m] on center along
the distribution run. Center the raceway sections together on the supports. Attach to the forms with suitable fasteners.
Fasten the raceway sections to the support brackets with self drilling screws to secure the raceway and insure ground
continuity. If grounding plates (RGP) are used, fillet weld or use suitable fasteners into subslab to electrically and
mechanically tie the raceways together. Use grounding plates only at the joints. Use duct tape to seal raceway joints.
Installation of Walkercell Raceway End Closures:
Place the L–Shaped end closure over the end of the Walkercell raceway. Secure the end plate in position with pop
rivets or welds.
Installation of PK Series Preset Inserts:
Orient the preset with the prepunched openings in the Walkercell raceway so that the rivet hole in the preset aligns
with the rivet hole in the center channel of the Walkercell raceway. Hook the preset under the end of the prepunched
holes in the raceway utilizing the two offset flanges on the preset. Slide the preset toward the hooked end until the
preset rivet hole is aligned with the rivet hole in the raceway. Secure the preset to the raceway with a 3/16" [4.8mm]
diameter pop rivet. Caulking around the preset is recommended if a plasticizer is used in the concrete.
22JB2510 Junction Box:
This box can be used when Walkercell is required to exit in more than two directions.
Concrete Placement and Curing:
Before concrete placement, make a final inspection of the entire Walkercell system. Any gaps in the system should be
sealed to prevent mortar or concrete from entering the system. Chloride salts such as calcium chloride shall not be
used in the concrete mix.
