SEPCO 434 Aluminum Clamp-On Service Entrance Cap, 4-Inch

The SEPCO 434 Aluminum Clamp-On Service Entrance Cap is a 4-Inch fitting built to terminate conduit at the point where service entrance conductors enter a structure. Formed from aluminum for a lightweight, corrosion-resistant fit, this clamp-on cap secures directly over the end of the conduit without threading, giving electricians and service crews a straightforward way to close out a service entrance run. Sized for 4-Inch service entrance conduit, it is suited to larger-capacity electrical services commonly found on commercial, industrial, and multi-family buildings where a substantial service disconnect or meter installation demands a wider raceway.

Key Features

  • Trade Size: 4-Inch, sized to match large-capacity service entrance conduit runs.
  • Durable Construction: Aluminum body resists corrosion and weathering while keeping the fitting lightweight for easier handling, lifting, and overhead installation.
  • Clamp-On Connection: Fits over the conduit end and clamps into place, eliminating the need to thread the cap onto the conduit and speeding up field installation.
  • Service Entrance Application: Purpose-built to cap the conduit at the utility service entrance point, the location where incoming overhead or underground service conductors transition into the building's raceway system.
  • Field-Ready Fit: The clamp-on design allows the 4-Inch cap to be positioned and secured on site without specialized tooling, simplifying service entrance work for electrical contractors.
  • Aluminum Weight Savings: Compared to heavier metal caps, the aluminum construction reduces the load on the conduit run and on installers working at height on service entrance masts.

SEPCO SEP434 – Frequently Asked Questions

1) Does the SEPCO 434 service entrance cap need threaded conduit?
No threading required. The 434 is a clamp-on cap, so it slips over the cut end of the conduit and clamps in place. That means you can use it on plain-end or field-cut 4-inch conduit without running a thread, which is the usual reason crews pick a clamp-on over a threaded entrance cap.
2) Is an aluminum service entrance cap OK for outdoor use on a weatherhead?
Yes. The 434 body is aluminum, which resists corrosion and weathering in an exposed service entrance location, and it keeps the fitting light enough to handle overhead on a mast. Weight matters when you are setting a 4-inch cap at the top of a riser from a ladder or bucket.
3) Where in the service does a 4-inch entrance cap like the SEPCO 434 go?
It caps the top of the conduit at the point where incoming service conductors enter the building raceway, overhead or underground feed. In practice that is the weatherhead position on a 4-inch mast or riser feeding a meter socket or service disconnect. The 434 is sized for the larger services typical of commercial, industrial and multi-family buildings.
4) Do I need special tools to install the SEPCO 434 cap?
No specialized tooling. The clamp-on design lets the cap be positioned on the conduit end and tightened down in the field, so there is no threading machine or die work involved on the 4-inch run.
5) What is the SEPCO part number for the 4-inch aluminum clamp-on entrance cap?
Order it as SEPCO 434. That single model covers the 4-inch aluminum clamp-on service entrance cap, so there are no finish or variation suffixes to specify.
