Manufacturing quality products for the electrical industry since 1926.

Mulberry has been an industry leader for over 90 years, supplying the electrical trade with an extensive offering of wallplates, box covers, weatherproof, and conduit bodies. We are dedicated to manufacturing quality electrical products in the USA. Almost all of our products are stamped, die-cast, machined, painted, assembled, and packaged domestically to assure customers of consistent quality and availability. Many of our products have innovations and features that have become industry standards.

As a family company, we pride ourselves on our product quality, broad selection and close customer relationships. Over 8000 items – including many that our competitors consider custom – are in stock at our NJ factory or our regional warehouses. Our broad and deep inventory enables us to ship orders fast (generally within 72 hours) and complete (with a 99% factory fill rate).

Whether you need an off-the-shelf box cover or a custom-made wallplate, we appreciate your contacting Mulberry and look forward to working with you.
