Orbit Industries SSLN-250 Steel Sealing Locknut 2-1/2 in

Product Description

The ORBIT INDUSTRIES SSLN-250 is a steel sealing locknut rated for 2-1/2 inch trade size conduit connections. It is designed to secure threaded conduits or connectors to electrical junction boxes and enclosures in wet and damp locations. A built-in gasket creates a watertight seal against the box surface, while serrated teeth bite into the enclosure to prevent loosening from vibration. The zinc electroplated steel construction provides corrosion resistance, extending service life in demanding environments. Licensed electricians install this hardware as part of weatherproof conduit runs in commercial and industrial applications.

The SSLN-250 is used wherever conduit enters a standard junction box or enclosure through an unthreaded knockout opening in a wet or damp location. It allows standard junction boxes to be brought into compliance for wet-location conduit terminations without requiring specialty enclosures. Typical installation scenarios include outdoor panels, wet utility rooms, rooftop mechanical areas, and below-grade electrical installations where moisture intrusion is a concern.

Key Features

• Gasketed sealing surface creates a watertight seal between the locknut and box or enclosure wall
• Serrated teeth grip the enclosure surface to resist vibratory loosening
• Zinc electroplated steel construction for corrosion resistance in damp environments
• 2-1/2 inch trade size fits corresponding conduit and connectors
• Enables use of standard junction boxes at wet-location conduit knockouts

Compatibility

Designed as an OEM-style sealing locknut for use with 2-1/2 inch trade size threaded conduit and connectors at standard junction box and enclosure knockouts in wet or damp locations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify power is off before working on any junction box or enclosure. Thread the locknut onto the conduit or connector and tighten firmly against the enclosure surface so the serrated teeth seat fully and the gasket compresses to form a watertight seal. Do not overtighten to the point of deforming the gasket, which would compromise the seal.
