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.

Key Features

  • Trade Size Range: Available in 3/4", 1", 2", and 2-1/2" trade sizes to match a variety of conduit diameters.
  • Durable Alloy Steel Construction: Alloy steel body provides strength and long-term durability for demanding electrical installations.
  • Insulated Throat Design: The insulated throat helps protect conductor insulation as wires pass through the hub into the enclosure.
  • Includes Locknut: Ships complete with a matching locknut for a secure, single-part conduit-to-enclosure connection.
  • Spec-Grade Quality: Manufactured to spec-grade standards for consistent, professional-grade performance on the job.
  • Complete Fitting Assembly: Hub and locknut are packaged together, reducing the need to source a separate locknut for installation.
  • Family of Sizes: Offered across 3/4", 1", 2", and 2-1/2" trade sizes, allowing one product line to serve multiple conduit diameters on the same job.

American Fittings AH100B – Frequently Asked Questions

1) Do I need to buy a separate locknut with the American Fittings AH hub?
No. Each AH hub ships with a matching locknut in the same package, so you have both halves of the conduit-to-enclosure connection in one part number. The locknut goes on the inside of the enclosure wall to draw the hub tight from the opposite side.
2) Why use an insulated throat hub instead of a plain conduit hub and a separate bushing?
The AH builds the insulation into the throat of the hub itself, so conductors pulled through the opening are protected from abrasion at the point of entry without stacking a separate insulating bushing on the fitting. Fewer loose parts on the truck, and one assembly to install with the included locknut. If you already stock plain hubs and grounding bushings for bonding work, that combination is a different animal; the AH is the single-piece answer where you just need the throat protected.
3) Is the American Fittings AH hub strong enough for industrial panel and switchgear work?
The AH body is alloy steel, not die-cast zinc or plastic, and it's built to spec-grade for commercial and industrial installs, including panelboards, junction boxes, motor control centers and switchgear entry points.
4) Can I standardize one hub line across a facility running several conduit sizes?
Yes, within limits. The AH family covers 3/4, 1, 2 and 2-1/2 inch trade sizes under a single product line and a consistent alloy steel, insulated-throat, locknut-included build, so an MRO or maintenance shop can stock one series for those four sizes. Anything outside those four trade sizes falls outside the family.
5) What part number do I order for a 2-1/2 inch insulated throat hub from American Fittings?
AH250B is the 2-1/2 inch size in the American Fittings AH insulated throat hub series, supplied with its matching locknut. The 2 inch is AH200B.
6) Where in an installation does a conduit hub like this actually go?
A hub is the transition point where a conduit run enters a panel, enclosure or box. The threaded body passes through the knockout, the locknut tightens it from the other side of the wall, and conductors pass out of the raceway into the equipment through the insulated throat. Typical spots are enclosure and cabinet entry points, junction boxes, panelboards and MCC wiring on both new construction and retrofit work.
