SEPCO CW58 CW Series Galvanized Steel Knockout Reducing Washer

The SEPCO CW58 CW Series Galvanized Steel Knockout Reducing Washer gives electricians a rugged, corrosion-resistant way to adapt conduit fittings and enclosure knockouts between trade sizes without re-drilling boxes or enclosures. Built from galvanized steel for a consistent, secure seat, this CW Series lineup is available in CW41 and CW62 model configurations to match different step-down needs on the job. It is a practical solution any time an existing panel, box, or enclosure has a larger opening than the conduit, connector, or fitting being installed, letting electricians reuse existing knockouts instead of modifying the enclosure itself.

Key Features

  • CW Series Design: Purpose-built reducing washer profile from the SEPCO CW Series for a consistent, reliable fit in electrical enclosures.
  • Durable Construction: Galvanized steel body resists corrosion and holds up to demanding indoor and outdoor electrical environments.
  • Model Options: Available in CW41 and CW62 configurations, giving electricians a range of step-down sizes to match conduit, connector, or knockout openings.
  • Versatile Fit: Steps a larger enclosure or knockout opening down to a smaller conduit, connector, or fitting size without re-drilling boxes or enclosures.
  • Protective Finish: Galvanized coating adds long-term protection against rust and wear on job sites and in the field.
  • Simple Installation: Drops into standard knockouts or openings to accept the reduced conduit or fitting size with no special tools required.
  • Job-Site Ready: Compact, low-profile design stacks and stores easily in a service truck or tool bag alongside other conduit fittings and hardware.

SEPCO CW41 – Frequently Asked Questions

1) What trade size reductions do the SEPCO CW Series reducing washers cover?
Two step-downs are offered. The CW41 takes a 1-1/4 inch knockout down to 1/2 inch, and the CW62 takes a 2 inch knockout down to 3/4 inch. Pick by the opening you already have in the box, not by the conduit alone.
2) My panel knockout is too big for the connector I'm installing. Can I use a reducing washer instead of swapping the enclosure?
That is exactly the job. A SEPCO CW Series galvanized steel reducing washer seats in the oversized knockout and accepts the smaller conduit, connector, or fitting, so you reuse the existing opening instead of re-drilling or replacing the box. Match the washer to the knockout size: CW41 for a 1-1/4 inch opening taking 1/2 inch, CW62 for a 2 inch opening taking 3/4 inch.
3) Are SEPCO CW reducing washers OK for outdoor or damp electrical enclosures?
The body is galvanized steel, which resists corrosion and holds up in both indoor and outdoor electrical environments per SEPCO. Note that a reducing washer is a mechanical adapter, not a sealing device, so wet-location integrity still comes from the fitting and the enclosure hub, not from the washer.
4) How do I order the right SEPCO reducing washer by part number?
Order by model: CW41 is the 1-1/4 inch to 1/2 inch washer, CW62 is the 2 inch to 3/4 inch washer. Both are SEPCO CW Series galvanized steel reducing washers, so the only choice you make is the step-down pair.
5) Do I need special tools to install a SEPCO CW reducing washer?
No special tools. The washer drops into a standard knockout or opening and accepts the reduced conduit or fitting size. In practice you still secure it the usual way, with the connector and locknut drawing the washer tight against the enclosure wall.
6) What kind of jobs are these reducing washers typically used on?
SEPCO lists them for conduit and raceway trade size reduction, panelboard and enclosure knockout adaptation, junction box and wireway fitting adaptation, commercial and industrial installations, renovation and retrofit wiring, and new construction rough-in. Retrofit work is where they earn their keep, since existing panels often have larger openings than the new conduit run.
