Description
TMI Metal Conduit Box System Circular 2 Way Box 3/4″ & 1″ Excellent for Heavy Duty Electrical Junction Box
The TMI Circular Metal Conduit Box 2 Way Through Box is a premium, robust component designed for creating straight, continuous runs in metal conduit systems while providing necessary access points.
Also known as a Through Box or C-Box, it features two opposing threaded outlets, allowing two lengths of rigid metal conduit (RMC) to be joined in a straight line, enabling the extension of a wiring system.
Constructed from durable, heavy-duty Galvanized Iron (GI) or Aluminium Alloy Die Casting, this junction box offers superior mechanical protection against impact and environmental wear, making it essential for demanding commercial and industrial environments.
Its metal construction ensures inherent fire resistance and provides an excellent, continuous path for grounding the entire electrical system, significantly enhancing safety.
The 2 Way Through Box is available in the common imperial sizes of 3/4 inch and 1 inch, or their metric equivalents of 20mm and 25mm, ensuring compatibility with standard GI conduit pipes.
It serves as a crucial point for pulling and splicing conductors, inspecting wiring, or performing maintenance without disturbing the entire conduit run.
For a professional, safe, and long-lasting installation that meets BS and MS Standards, the TMI 2 Way Through Box is the reliable choice for all heavy-duty wiring applications.
