FAQs
MHUB3 HDG is a 1" trade size conduit hub made from malleable iron with a hot-dip galvanized finish, designed to mate securely with standard 1" conduit runs and compatible enclosure knockouts. Its compact dimensions support tight panel layouts, reducing the risk of misalignment and ensuring a dependable seal against dust and moisture in ordinary locations.
Key specs include 2.06 in length, 1.79 in height, 1.81 in width, and a weight of 0.5 lb. These dimensions simplify fitment in constrained spaces and enable straightforward mounting alongside other Crouse-Hinds components. The malleable iron construction provides robust shear and torque resistance for secure conduit retention.
MHUB3 HDG is certified for Ordinary/Non-Hazardous Locations and adheres to NEC/CEC standards, with UL certification for commercial hubs in the US and Canada. While it offers corrosion protection via hot-dip galvanizing, it is not rated for hazardous locations or outdoor exposure beyond ordinary non-hazardous environments without additional protection.
The hub complies with NEC/CEC standards and is UL-listed for commercial hubs in the US and Canada. This combination supports regulatory acceptance and reliable performance in commercial and industrial installations, facilitating smoother inspections and compliance reporting across North America.
The hot-dip galvanized finish offers superior corrosion resistance, which translates to longer service life and reduced maintenance in challenging environments. The durable malleable iron body minimizes service calls due to mechanical wear, and its standardized 1" trade size accelerates procurement and project planning, delivering a favorable total cost of ownership.
