For Faster, Easier GRC Installations Make It Kwik-Couple

  • No separate couplings to purchase, store, carry or install
  • High grade robust and ductile steel for long life
  • Corrosion resistant exterior and interior finishes
  • Certified to CSA Safety Standard C22.2 No.45.1
  • Kwik-Couple Rigid Conduit is available in trade sizes 2-1/2 to 5*

*Kwik-Couple Rigid Conduit does not contain a listing for wet locations and has not been evaluated for Class I Division 1 locations.

Full Electrical System Protection

Manufactured from mild steel, Columbia-MBF Kwik-Couple Rigid Conduit is extremely resistant to damage from impact yet ductile to facilitate bending.

The 3/4″ taper NPT threads (ANSI B1.20.1) are full cut and hot galvanized after cutting. Color-coded end cap thread protectors keep the threads clean, sharp and also provide immediate trade size recognition. Even sizes are color-coded blue and 1/2 sizes black.


Hot-dip galvanized throughout to deliver galvanic corrosion protection. Top-coated with a compatible organic layer to protect against white rust. The inside surface is evenly coated for quick and ease of wire-pulling, even through multiple 90° bends.

EMI Shielding

Columbia-MBF Kwik-Couple Conduit is highly effective in decreasing the effects of electromagnetic field levels for encased power distribution circuits, shielding computers and other sensitive electronic equipment from the effects of electromagnetic interference.

Codes & Standards Compliance

Columbia-MBF Kwik-Couple GRC Conduit is precision manufactured for reliable, extended value and supreme protection for electrical conductors. Covered by Section 12 of the Canadian Electrical Code (CEC), rigid steel conduit is highly resistant to damage from impact. Rigid steel conduit functions as an equipment bonding conductor when installed in accordance with the Canadian Electrical Code including Section10 Grounding and Bonding and Section 12-100 Rigid and flexible metal conduit.

Kwik-Couple Rigid steel conduit is certified to Canadian Standards Association Safety Standard C22.2 No.45.1 and C22.2 No.18.3.and is manufactured in accordance with ANSI C80.1. Kwik-Couple Rigid Steel conduit is listed for Concrete-tight applications.

Installation of Rigid Conduit shall be in accordance with the Canadian Electrical Code and CSA General Information.

Specification Data

Kwik-Couple Rigid Conduit shall be certified to CSA Safety Standard C22.2 NO.45 and C22.2 No.18.3. Kwik-Couple Rigid Conduit is manufactured in accordance with ANSI C80.1.
