Solid-Wall Wiring Duct

This solid-wall wiring duct provides enclosed cable routing for electrical panels and control cabinets. The 72-inch length covers long runs in industrial and commercial installations. Gray lead-free PVC meets UL 94V-0 flammability requirements.

Replaces Open Tray Systems

Snap-on covers and 0.2-inch finger slots protect conductors better than open cable trays while still allowing easy wire breakout. The upgrade is worth it when codes require flame-rated enclosures or when physical damage risk is high.

CE, CSA, UL 94V-0 and NFPA 79 Limits

The duct carries CE, CSA, RU and UL 94V-0 markings and meets NFPA 79-2015 section 13.3.1 for industrial machinery wiring. It does not satisfy liquid-tight or hazardous-location conduit standards.

Questions about this item

What screw size is needed to mount the 3 1/4 in wide duct?

The duct uses a screw-mount style; select fasteners that suit the mounting surface and the duct's base slots.

How do you attach the snap-on cover without cracking the PVC?

Align the cover with the duct edges and press firmly along the length until it seats; avoid prying or excessive force on the solid wall.

When should the gray PVC duct be replaced due to UV exposure?

Replace if the material becomes brittle, discolored, or shows surface cracking, as UV degradation can compromise the UL 94V-0 rating.
