Arlington Industries RW38 Red Washer 4x0.75 Inch

Product Description

The ARLINGTON INDUSTRIES RW38 is a red washer designed for use in electrical and low-voltage installation work. Measuring 4 inches in outer diameter with a 0.75-inch inner diameter, this washer provides a visible, color-coded identification layer at conduit, fitting, or panel penetrations. The red color serves as a quick visual indicator commonly used in electrical rough-in and finishing applications. Electricians and installers reach for this type of washer when a secure, color-coded seal or spacer is needed at a junction or entry point. Sold individually, the RW38 is a straightforward hardware accessory built for field use.

This washer is suited for residential and light commercial electrical installations. It is typically used at conduit entries, knockout openings, or panel penetrations where a color-coded identifier or protective gasket layer is required. The 4-inch outer diameter accommodates standard large-knockout and fitting applications, while the 0.75-inch inner diameter fits common conduit and fitting sizes found in everyday electrical work.

Installation Notes

Installation is typically performed by a licensed electrician as part of conduit or panel work. Power down and de-energize all circuits in the work area before installing or replacing washers at panel or junction penetrations. Follow applicable NEC requirements for the installation type and location. No special tools are required for placement, but ensure the washer seats flush and the inner diameter aligns cleanly with the conduit or fitting before securing.
