When your design demands the ultimate in corrosion resistance, Auroralight's Recessed Junction Box offers a solid solution. 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. The RJB also provides a "rock solid" foundation upon which to attach our versatile ES Fixture Extension System. 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; ideal for stone veneer applications.
