Abb 1247 Malleable Iron Enlarger Bushing 1-1/4 X 1-1/2 in

Product Description

The ABB 1247 is a malleable iron enlarger bushing designed to transition conduit or pipe threads from a 1-1/4 inch female opening to a 1-1/2 inch male thread. This type of fitting is a standard component in electrical conduit systems, used to adapt knockouts, enclosures, or fittings where thread sizes do not match directly. Licensed electricians and conduit installers rely on enlarger bushings like this to make clean, code-compliant transitions without additional adapters. The malleable iron construction provides durability and resistance to mechanical stress in both exposed and concealed installations.

The ABB 1247 is suited for use in residential and commercial electrical conduit assemblies wherever a 1-1/4 inch to 1-1/2 inch thread enlargement is required. Common applications include panel enclosures, junction boxes, and conduit bodies where knockout or hub sizes need to be stepped up to accept a larger conduit or fitting. This bushing is installed by electricians working with rigid metal conduit or intermediate metal conduit systems.

Key Features

• Malleable iron construction for strength and long-term durability
• 1-1/4 inch female to 1-1/2 inch male thread configuration
• Enlarger design allows upsizing of conduit thread connections at enclosures and fittings
• Compact form factor fits standard knockout and hub installations

Compatibility

Designed as an OEM-style replacement or standard-stock enlarger bushing for use in rigid metal conduit and intermediate metal conduit systems requiring a 1-1/4 inch to 1-1/2 inch thread transition.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for conduit fittings and enclosures. De-energize all circuits and verify power is off before working inside any panel or enclosure. Thread the bushing by hand first to confirm correct thread engagement before applying a pipe wrench or strap wrench to seat the fitting. Do not overtighten, as malleable iron fittings can crack under excessive torque.
