Abb 321-TB 3/8 in 90 Degree Flex Conduit Connector 50 Pack

Product Description

The ABB 321-TB is a 3/8 inch, 90-degree self-screw flexible conduit connector designed for use in electrical raceway systems. This fitting secures flexible metallic or non-metallic conduit at a 90-degree angle, allowing directional transitions in tight or space-constrained enclosures. The self-screw design eliminates the need for separate locknuts in many applications, reducing installation steps. Licensed electricians and electrical contractors install this type of connector when routing flexible conduit into junction boxes, panels, or equipment enclosures where a right-angle entry point is required.

This connector is suited for commercial and residential electrical installations where 3/8 inch flexible conduit must make a 90-degree turn at a termination point. Common applications include motor connections, HVAC equipment wiring, and control panel builds where flexible conduit provides vibration isolation or final-run flexibility. It is sold in a 50-piece pack, making it practical for contractors stocking service vehicles or completing larger panel and equipment installations.

Key Features

• 3/8 inch trade size for standard flexible conduit compatibility
• 90-degree angle body for right-angle conduit entry at enclosures and boxes
• Self-screw design simplifies termination and reduces hardware count
• Sold in a 50-piece pack for job-site and van-stock efficiency
• Compact form factor suited for tight enclosure knockouts

Compatibility

Designed as an OEM-style fitting for use with 3/8 inch flexible conduit in standard electrical raceway applications.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 350 or applicable local codes governing flexible conduit systems. De-energize the circuit and verify lockout-tagout procedures are complete before terminating conduit at any enclosure. Ensure the knockout size matches the 3/8 inch trade size before installation. Do not overtighten the self-screw mechanism, as doing so may damage the conduit jacket or fitting threads.
