Southwire MR16 Reducing Washer 2 to 1.5 Inch

Product Description

The SOUTHWIRE MR16 is a reducing washer designed to adapt a 2-inch knockout opening to accept a 1.5-inch conduit fitting or connector. These washers are used in electrical enclosures, panels, and junction boxes where the existing knockout is larger than the fitting being installed. The MR16 allows electricians to make use of existing knockouts without requiring a new enclosure or rework of the box. Installation is straightforward and requires no special tools, making it a common item on commercial and residential electrical jobs.

Reducing washers like the MR16 are standard inventory for electricians working on panel installations, service upgrades, and junction box assemblies. They are used wherever a conduit fitting, connector, or locknut must seat into a knockout that is one trade size larger than the fitting itself. This part adapts a 2-inch knockout to a 1.5-inch fitting, one of the most common reducer combinations in commercial and residential electrical work.

Key Features

• Adapts 2-inch knockouts to accept 1.5-inch conduit fittings and connectors
• Flat washer profile seats flush against the enclosure wall for a secure, clean fit
• Compatible with standard locknuts and connectors used in conduit installations
• Compact form factor fits easily into enclosures and panels without clearance issues

Compatibility

Designed as a standard reducing washer for use in electrical enclosures, panel boxes, and junction boxes with 2-inch knockouts requiring a 1.5-inch conduit fitting or connector.

Installation Notes

Reducing washers are installed by licensed electricians in accordance with NEC requirements for conduit and fitting installations. De-energize the panel or enclosure before beginning any work on knockouts or fittings. The washer is placed over the knockout opening and held in place by the conduit connector locknut when tightened. Do not force or bend the washer, as deformation can prevent a proper seal against the enclosure wall.
