Hubbell CUP5 Recessed Head Plug 1-1/2 Inches

Product Description

The HUBBELL CUP5 is a 1-1/2-inch recessed head plug designed for use in electrical wiring systems where a flush or recessed termination point is required. This plug seats below the surface of the fitting or enclosure, reducing the risk of accidental contact or mechanical damage to the connection point. It is a compact, durable fitting suited for installation by licensed electricians in commercial and industrial applications where clean, protected terminations are a priority.

The CUP5 is typically used in conduit or enclosure installations where a recessed plug profile is specified. Its 1-1/2-inch sizing fits standard trade-size openings and is appropriate for use in junction boxes, enclosures, or conduit bodies requiring a secure, recessed closure. It suits both new construction and retrofit scenarios handled by electrical contractors working to NEC standards.

Key Features

• Recessed head design minimizes protrusion and protects the plug from accidental impact
• 1-1/2-inch trade size fits standard electrical fittings and enclosures
• Compact profile supports clean, professional termination finishes

Compatibility

Designed as an OEM-style replacement or direct-fit plug for standard 1-1/2-inch trade-size electrical enclosures, conduit bodies, and junction box openings.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before beginning any work on the enclosure or conduit body. Verify trade-size compatibility with the fitting or enclosure before installation. Do not over-tighten, as this may damage the plug body or the mating threads.
