Arlington 149 4-inch Clamp Type Entrance Cap

Product Description

The ARLINGTON 149 is a 4-inch clamp-type entrance cap designed for electrical service entry applications. It secures and weatherproofs the point where service entrance conductors enter the riser conduit, protecting the connection from moisture and debris. Electricians install this fitting as part of an overhead service entrance assembly on residential and light commercial structures. The clamp-style design allows for secure attachment to the service riser conduit without the need for threading, simplifying installation in the field. Weighing 4.294 pounds, it is built for durable, long-term outdoor service.

This entrance cap is used in overhead electrical service entrance installations where a 4-inch conduit riser carries service conductors from the utility drop to the meter base or service panel. It is suited for residential and light commercial applications and is installed by licensed electricians during new construction or service upgrade projects. The clamp-type attachment method is appropriate where conduit threading is not practical or available on site.

Key Features

• 4-inch trade size fits standard 4-inch service entrance conduit risers
• Clamp-type design eliminates the need for threaded conduit ends

Compatibility

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and coordinate with the utility provider before working on or near service entrance conductors, as the line side of the service entrance is utility-controlled and may remain energized. Ensure the cap is oriented correctly to shed water away from the conduit opening. Inspect the clamp hardware for proper seating and secure engagement with the conduit before completing the installation.
