Kwik & Specialty Conduit

Columbia-MBF Kwik products are available in Electrical Metallic Tubing (EMT) and Galvanized Rigid Steel Conduit (GRC). Columbia-MBF patented an innovative design which allows for a coupling or fitting to be an integral part of the conduit. This integral coupling/fitting allows installers to put together conduit systems quicker.

True Color Conduit made by Columbia-MBF allows you to quickly identify circuits. By adding a color to the top coat applied to our conduit, Columbia-MBF is able to provide distributors and installers with pre-colored raceways designed with specific circuits in mind. No more need to spend time painting Conduit in the field.
