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 entire fixture installation’s longevity. It is recommended for extreme coastal conditions where typical components will rapidly fail and for installations requiring maximum mounting strength. The optional Mounting Bracket [MB] connects the J-Box directly to the building’s structure, 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.
