The RJB Recessed J-Box is possibly the most robust and ultimate corrosion resistant J-Box available. The RJB is machined from solid brass ensuring the longevity of the entire fixture installation. Recommended for extreme coastal conditions where normal components will rapidly fail and for installations requiring maximum mounting strength. The optional Mounting Bracket [MB] connects the J-Box directly to structural building components, ensuring a robust mount point ideal for single heavier fixtures or multiple fixture installations. Available in 18 and 22 cubic inch sizes with a choice of machined brass extensions to increase volume or flush the face to finished surfaces, the RJB solves many issues found in construction and is especially ideal for stone veneer applications. Pair the RJB with one of our many canopies and fixtures for the strongest combination of products on the market.
