Appleton WPLG754 Weatherproof Closure Plug 3/4 in Gray

Product Description

The APPLETON WPLG754 is a closure-type plug designed to seal unused knockout openings in weatherproof outlet boxes. Sold as a pack of four, each plug fits a 3/4 inch trade size knockout and is molded in gray. The plug blocks moisture, dust, and debris from entering the enclosure through open knockouts, maintaining the integrity of the weatherproof rating of the box. Licensed electricians and maintenance technicians install this fitting during new construction, panel box work, or service calls where unused knockouts need to be properly sealed per code requirements.

This closure plug is suited for residential and light commercial electrical installations wherever weatherproof outlet boxes are used — exterior walls, outdoor receptacle locations, irrigation control enclosures, and similar wet or damp location applications. The gray color blends with standard gray weatherproof box finishes. Each bag contains four plugs, making it practical to stock for service vans or job-site use where multiple knockouts may need to be closed in a single visit.
