Orbit Industries SSLN-150 Steel Sealing Locknut 1-1/2 in

Product Description

The ORBIT INDUSTRIES SSLN-150 is a steel sealing locknut designed to secure threaded conduits or connectors to electrical junction boxes and enclosures in wet and damp locations. The locknut features a gasketed seating surface that forms a water-tight seal against the box face, keeping moisture out of the enclosure. Serrated teeth on the locking face bite into the box wall to resist vibratory loosening over time. A zinc electroplated finish adds corrosion resistance, making this locknut suitable for both wet and damp installation environments. Licensed electricians and conduit installers use this fitting as part of a compliant wet-location wiring system.

The SSLN-150 is sized for 1-1/2 inch trade size conduit openings. It allows standard junction boxes and enclosures with unthreaded knockout openings to accept conduit or connectors in wet locations without requiring a specialty box. Typical applications include outdoor panels, weatherproof enclosures, industrial junction boxes, and any wet or damp conduit installation where a positive, sealed connection at the box knockout is required.

Compatibility

Designed as an OEM-style replacement and standard-fit sealing locknut for 1-1/2 inch trade size threaded conduit connectors and conduit ends used with electrical junction boxes and enclosures in wet or damp locations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for wet and damp location wiring methods. De-energize the circuit and verify power is off before working on any enclosure or junction box. Thread the locknut onto the conduit or connector and tighten against the box knockout until the gasket seats firmly and the serrated teeth fully engage the enclosure surface. Do not over-tighten to the point of deforming the gasket, as this can compromise the water-tight seal.
