Southwire L37-1 Emt Offset Connector 1/2 Inch

Product Description

The SOUTHWIRE L37-1 is a 1/2-inch EMT offset box connector designed to secure electrical metallic tubing to a junction box or enclosure when a straight-entry connector is not practical. Constructed from zinc die cast, this set screw-style fitting provides a concrete-tight seal when taped, making it suitable for installations where moisture or concrete embedment is a concern. The offset design allows the conduit to meet the box face at a slight angle, reducing stress on the raceway and simplifying rough-in work in tight spaces. Licensed electricians and electrical contractors are the primary installers of this fitting.

This connector is used in residential and commercial electrical installations where 1/2-inch EMT conduit must terminate at a metallic box or enclosure. The offset configuration is especially useful when conduit runs are close to walls or structural elements that prevent a flush straight-entry approach. It is suited for use in dry, damp, and concrete-form applications when taped per installation requirements. Compliance with UL514B confirms the fitting meets recognized standards for conduit connectors and fittings.

Key Features

• Offset design connects 1/2-inch EMT to a box or enclosure where straight entry is restricted
• Zinc die cast construction provides durability and corrosion resistance in standard electrical environments
• Concrete-tight rating achieved when taped, suitable for slab or form-in-place installations
• Set screw fastening secures EMT conduit without tools beyond a standard screwdriver or hex key
• Meets UL514B requirements for conduit connectors and fittings

Compatibility

Designed as an OEM-style replacement and standard trade fitting for 1/2-inch EMT conduit systems terminating at metallic boxes or enclosures in residential and commercial electrical applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the affected enclosure before beginning work. Insert the EMT conduit fully into the connector and tighten the set screw securely to ensure a solid mechanical and electrical bond. When a concrete-tight rating is required, apply tape over the connector per standard practice before pouring or encasement.
