Thomas Betts ALB-4 Lb Conduit Body 1-1/4 Inch Imc Rigid Aluminum

Product Description

The THOMAS BETTS ALB-4 is an LB-style aluminum conduit body designed for 1-1/4 inch trade size IMC and rigid metallic conduit systems. The oval body configuration provides 32 cubic centimeters of interior volume, meeting NEC fill requirements for conductor splicing and pulling. At 1.18 pounds, this fitting is lightweight without sacrificing structural integrity. Licensed electricians and electrical contractors install this type of fitting when a 90-degree change of direction is required in an exposed or concealed conduit run, or when wire pulling access is needed at a junction point.

This conduit body is suited for commercial and industrial electrical installations where IMC or rigid aluminum conduit is specified. The gray aluminum construction and weather-resistant rating make it appropriate for both indoor and outdoor applications. It is commonly installed at wall-to-ceiling transitions, service entrance routing, and in-wall junction points where code requires accessible conductor capacity. Electricians working on exposed conduit runs in industrial plants, commercial buildings, and utility service applications will find this fitting compatible with standard rigid and IMC system layouts.

Installation Notes

Installation of conduit bodies must be performed by a licensed electrician in accordance with NFPA 70 (NEC) Article 314 and applicable local codes. De-energize the circuit and verify absence of voltage before opening any conduit body for wire pulling or splicing. Secure the conduit body with appropriate locknuts or fittings rated for IMC or rigid conduit. Do not exceed the listed conductor fill capacity of the body when routing or splicing conductors.
