Product Innovation & Excellence

Columbia-MBF has a specified line of EMT. Columbia-MBF EMT and EMT Elbows, includes specialty Kwik-Fit®, Kwik-Fit® Compression, and True Color EMT and EMT elbows with E-Z Pull® interior finish for easier wire pulling and an exterior galvanizing process proven to last. Columbia-MBF’s Kwik-Fit® EMT has an integral steel setscrew coupling and the Kwik-Fit® Compression EMT features built-in steel compression coupling. These innovative built-in couplings significantly reduce installation time up to 50%*, and eliminate the need to purchase, store, and install separate couplings. Columbia-MBF’s True Color EMT provides instant identification of individual power, data com, and emergency electrical systems. The 8 bright colors eliminate the need to spray, powder coat or tape in the field so installation is quicker, easier and safer.

Columbia-MBF’s Hot-Dip galvanized rigid conduit manufactured from high strength ductile steel provides excellent corrosion resistance. The conduit, installed with Columbia-MBF’s elbows, couplings and nipples provides a smooth, continuous raceway. Columbia-MBF’s Kwik-Couple® Hot-Dip galvanized rigid conduit and elbows have factory-installed couplings. These couplings eliminate the need to buy expensive unions or 3-piece couplings. Simply line up the conduit ends, spin the Kwik-Couple® coupling forward onto the next piece, then wrench-tighten, eliminating the need to rotate the heavy conduit or elbows.

Columbia-MBF offers a broad line of rigid Aluminum conduit, elbows, couplings, and nipples. Columbia-MBF’s Aluminum combines light weight and corrosion resistance to provide a full-line of easy to install, low maintenance conduit whenever specifications call for aluminum.

We also sell AFC Cable Systems® complete lines of AFC FittingsFlexible Metal Conduit, and Liquid-Tuff Liquid Tight Flexible Conduit.

Our agents, sales and customer service teams are available to assist with questions on application, installation and availability of our products. Thank you for considering Columbia-MBF for your conduit and fitting requirements.
