American Fittings AH Alloy Steel Insulated Throat Hub with Locknut, Spec-Grade

American Fittings AH Alloy Steel Insulated Throat Hub with Locknut, Spec-Grade

American Fittings AH insulated throat hubs are alloy steel conduit fittings engineered for secure, insulated conduit-to-enclosure connections. This spec-grade hub is available in trade sizes ranging from 3/4" up to 2-1/2" (3/4", 1", 2", and 2-1/2") to cover a broad range of conduit diameters. Each hub ships complete with a matching locknut, giving installers a durable, alloy steel fitting built for demanding commercial and industrial electrical work.

As a conduit hub, the AH provides the connection point where conduit enters a panel, enclosure, or box, helping route conductors from the raceway into the equipment. The insulated throat is designed to help guard conductor insulation from abrasion at the point of entry, while the included locknut secures the fitting from the opposite side of the enclosure wall for a finished, professional installation.
