Features & Specifications

Manufactured for Long Life

Columbia-MBF EMT is precision manufactured from high grade mild strip steel for exceptional durability and long-lasting life. Columbia-MBF EMT is hot galvanized using a patented inline Flo-Coat® process. This process combines zinc, a conversion coating, and a clear organic polymer topcoat to form a triple layer of protection against corrosion and abrasion. E-Z Pull® EMT combines strength with ductility, providing easy bending, cutting and joining while resisting flattening, kinking and splitting. Available in sizes 1/2 (16) – 4 (103).


Columbia-MBF ’s EMT (Electrical Metallic Tubing) has a special low friction ID coating called E-Z Pull® that greatly improves the slip properties between conduit and wire. With E-Z Pull® EMT, wire pulls through the EMT smoothly and easily, making installation easier and faster.

EMI Shielding

Columbia-MBF EMT is very effective in reducing electromagnetic field levels for encased power distribution circuits, shielding computers and other sensitive electronic equipment from the effects of electromagnetic interference. Find more information on EMT shielding via the GEMI (Grounding and Electro-Magnetic Interference) software analysis program.

Codes & Standards Compliance

Columbia-MBF E-Z Pull® EMT is certified to Canadian Standards Association C22.2 No. 83.1. As a metal raceway, EMT functions as an equipment bonding conductor when installed in compliance with the Canadian Electrical Code (CEC), including Section 10 Grounding and Bonding and Section 12-1400 Electrical Metallic Tubing. Documentation is available in the GEMI (Grounding and Electro-Magnetic Interference) analysis software and related research studies.
