Industrial settings with harsh working conditions require the proper flanged enclosure to achieve superior durability, ease of installation, versatility, and resistance to extreme temperatures and environmental conditions. At Hope Electrical Products Co., Inc., we offer an ideal solution that addresses all of these requirements: the H7000 Type Flanged Recessed Cover Box. This NEMA-rated product features high-impact construction and a flush-mount design to provide lasting service in nearly any public-sector or commercial application.
Understanding NEMA Ratings for Flanged Cover Boxes
The National Electrical Manufacturers Association (NEMA) has established a standard rating system that determines the specific environments with which an electrical enclosure is compatible. These ratings aim to benefit both manufacturers and end users so that enclosures will provide safe, durable, and long-lasting performance.
Maintaining its integrity despite exposure to dust, water splashes, rain, or sleet, the H7000 cover box meets NEMA 3R and NEMA 4 box ratings. The NEMA 3R rating confirms that the H7000 Type provides sufficient protection against precipitation and ice buildup.
In addition, this cover box type adheres to UL 50 standards, meaning that it has withstood thorough testing to ensure the end product provides sufficient safety, structural integrity, and ingress protection, regardless of physical stress. As a result, our clients seeking solutions for regulated infrastructure applications can rest assured that their equipment will meet their requirements.
Material and Build Quality for Long-Term Durability
The H7000 Type is available in cast iron or cast aluminum, with cast iron being the standard cover box construction. These options allow customers to select between a cover box that offers a degree of corrosion resistance and one with maximum load capacity. Regardless of the option you choose, both benefit from hot-dipped galvanization to improve durability in the face of the elements, making the H7000 particularly good for chemical, coastal, or exterior environments.
To create a seal that’s both water- and airtight, each unit comes with a neoprene gasket and machine screws of stainless steel construction. These components enhance longevity by protecting against the following:
- Oils
- Solvents
- UV Exposure
If you require even more protection in environments with heavy foot or vehicle traffic, we offer heavy-duty units with checkered bronze or steel covers. You might use these for street-level access points, sidewalk boxes, or utility areas with frequent vehicle traffic.
Mounting and Customization Options for Harsh Use
The H7000 cover box works for standard surface mounting as well as flush concrete mounting installations. This capability adds some flexibility to the H7000 cover box. It’s also well-suited for retrofitting existing systems or designing new builds in areas with tight space restrictions or applications with critical security and aesthetic requirements. Flush mounting is especially important for protecting against potential tampering and impact.
For even more adaptability in meeting specialized field and mounting requirements, the H7000 is available with multiple upgrades or options, including:
- Back Plates
- Grounding Lugs
- Special Gaskets
- Plain Brass or Checkered Bronze Covers for Enhanced Corrosion Protection
- Tapping for Conduit Fittings
- Pre-drilled Holes
- Internal Bosses
The compact design and potential for customization make this product suitable for use in sidewalk power delivery, traffic control, lighting access, and more.
