A round knockout seal is an essential electrical fitting component designed to close unused knockout openings in electrical boxes and fittings. These small but critical seals prevent dust, debris, and moisture from entering electrical enclosures, which can compromise system integrity. Whether you are a professional electrician or a DIY enthusiast, a quality knockout seal is a practical choice for both residential and commercial electrical projects.
The Sigma Engineered Solutions ProConnex Round Knockout Seal is constructed from durable zinc-plated steel, offering corrosion resistance and a professional appearance that blends seamlessly with standard electrical hardware. By sealing off unused knockouts, this fitting helps prevent moisture-related failures and maintains the efficiency of your electrical systems.
