Square D A125 Hub

The Square D A125 1-1/4 in hub is a Type A conduit hub designed for use with Square D meter sockets and CSEDs, featuring a four-hole mounting pattern that matches standard A openings. It accepts conduit trade size 1-1/4 in and measures about 3.3 in square with an approximate weight of 0.23 lb per hub, sold as a single unit. This hub is UL listed, CSA listed, and ANSI certified for use with Square D metering equipment, including outdoor, rainproof installations in NEMA 3R contexts where A-series hubs are specified. The A125 is cataloged as the 1.25 in option in Square D’s hub family, and is shown alongside other A-type hubs for meter-pak and CSED configurations. Some listings, such as Crescent Electric, note a rainproof variant of the A125 for meter-pak assemblies, reflecting its suitability for weather-exposed installations.
