SEPCO CW Series Recessed Flat Reducing Washer, Galvanized Steel

The SEPCO CW Series is a family of 21 recessed flat reducing washers, including CW106, CW108, CW21, CW31, CW32, CW42, CW43, and CW51 through CW87, each built from galvanized steel to step a larger conduit, box, or enclosure opening down to a smaller diameter for a clean, secure reduction point. Every model shares the same recessed flat profile, which seats flush against the mounting surface rather than sitting proud of the surrounding metal. The CW106, for example, reduces a 4-Inch opening to 2-Inch, illustrating the kind of size transition available across the series for commercial and industrial electrical installations where a reliable, code-compliant reduction is required, and the same low-profile approach carries through every other model in the lineup.

Key Features

  • CW Series Model Range: 21 models, including CW106, CW108, CW21, CW31, CW32, CW42, CW43, and CW51 through CW87, cover a range of conduit and box opening reductions so installers can select the exact step-down needed for the job.
  • Durable Construction: Galvanized steel body resists corrosion and rust, supporting long-term performance in demanding indoor and outdoor electrical environments.
  • Recessed Flat Design: The recessed flat profile seats securely and flush against the mounting surface, minimizing protrusion and providing a clean, professional installation appearance.
  • Sample Reduction: The CW106 model reduces a 4-Inch opening to 2-Inch, representative of the size transitions available across the CW Series.
  • Consistent Fit and Finish: Every model in the CW Series is engineered for consistent gauge and finish, so installers get predictable results whichever model the job calls for.
  • Versatile Reduction: Well suited for adapting conduit bodies, panelboards, boxes, and enclosures where a size step-down is needed without swapping the entire fitting.
  • Installer-Friendly: Flat, uniform gauge steel is easy to handle and position during rough-in, helping keep installation times on schedule for electrical contractors.

SEPCO CW32 – Frequently Asked Questions

1) What size step-downs are available in the SEPCO CW Series reducing washers?
The CW Series covers 21 reductions, from small trade sizes up to 4 inch openings: 3/4 to 1/2 (CW21), 1 to 1/2 (CW31), 1 to 3/4 (CW32), 1-1/4 to 3/4 (CW42), 1-1/4 to 1 (CW43), 1-1/2 to 1/2 (CW51), 1-1/2 to 3/4 (CW52), 1-1/2 to 1 (CW53), 1-1/2 to 1-1/4 (CW54), 2 to 1 (CW63), 2 to 1-1/4 (CW64), 2 to 1-1/2 (CW65), 2-1/2 to 1 (CW73), 2-1/2 to 1-1/4 (CW74), 2-1/2 to 1-1/2 (CW75), 2-1/2 to 2 (CW76), 3 to 1-1/2 (CW85), 3 to 2 (CW86), 3 to 2-1/2 (CW87), 4 to 2 (CW106) and 4 to 3 (CW108).
2) I have a 2 inch knockout in a panelboard and I'm running 1 inch conduit. Which CW washer do I need?
Use the CW63, which steps a 2 inch opening down to 1 inch. Reducing washers are normally used in pairs, one on each side of the sheet metal, so the fitting locknut and bushing seat squarely on the knockout. If your conduit is 1-1/4 inch instead, order the CW64; for 1-1/2 inch, the CW65.
3) Can I use a reducing washer instead of replacing an oversized knockout during a remodel?
That is the normal use. When an existing box, panelboard, or conduit body has a knockout larger than the raceway you are bringing in, a pair of CW washers closes the gap so you can land the correct size connector without changing the enclosure or the fitting. Common renovation picks are the CW86 for a 3 inch hole taking 2 inch conduit, and the CW106 for a 4 inch hole taking 2 inch.
4) What's the difference between a recessed reducing washer and a flat plate washer?
The CW Series uses a recessed flat profile, so the washer seats flush against the box or enclosure wall instead of standing proud of the surrounding metal. That keeps the bushing or connector shoulder down inside the recess, which matters when a cover, trim ring, or panel dead front has to sit tight over the fitting. A plain flat washer with no recess adds its full thickness to the stack-up and can interfere with covers.
5) Are SEPCO CW reducing washers OK for outdoor or damp enclosures?
The CW washers are galvanized steel, which resists corrosion and rust for indoor and outdoor electrical use. Keep in mind a reducing washer is not a seal: it fills the oversize hole mechanically. If the enclosure has to stay watertight, the raintight fitting and its gasket do that job, not the washer.
6) Is the smallest CW washer able to take a 3/4 inch knockout down to 1/2 inch?
Yes, that is the CW21, the smallest step-down in the series. Below that there is nothing smaller in the CW lineup, so a 1/2 inch knockout needing further reduction is handled with a chase nipple or a bushing rather than a washer.
7) How many reducing washers do I order per hole?
Plan on two per opening for a standard knockout reduction, one on the outside and one on the inside of the enclosure wall, so the connector is centered and the locknut pulls up on steel rather than air. Order the same model for both sides, for example two CW54 for a 1-1/2 inch knockout taking 1-1/4 inch conduit.
8) Will a CW washer let me jump more than one trade size in a single step?
Yes, several models skip sizes. The CW51 takes 1-1/2 inch down to 1/2 inch, the CW73 takes 2-1/2 inch down to 1 inch, and the CW85 takes 3 inch down to 1-1/2 inch. If the jump you need is not in the series, do it in two stages or change the enclosure knockout.
9) Do CW Series washers work with rigid and IMC conduit systems?
Yes. The CW washers are intended for rigid and intermediate metal conduit system transitions, along with panelboard, box, and enclosure knockout reductions on commercial and industrial jobs. Size by the knockout you have and the trade size of the fitting going into it.
