This plastic-reinforced gland plate covers cable entry and exit cutouts on SmartRack NEMA 3R and NEMA 4 industrial enclosures, including the SRN and SRIN series. The SRGP4PLASTIC allows you to easily drill or cut holes to exactly match cable fittings or conduit diameter. It resists weather and corrosion, making it ideal for outdoor use, as well as food, beverage and pharmaceutical facilities where hot water and chemicals are used to clean and sanitize surfaces.
