IronRidge JayBox Rail Mounted Junction Box

JayBox® is an ever-adaptable junction box, designed to securely enclose wires on nearly any solar project—with ample space to shelter up to 4 module strings. The box is UL-listed, NEMA-3R-rated, and supports up to 1500-volt systems. It is made of a NORYL™ resin, known for its long-lasting UV-resistance and impact strength. Mounting Type: JayBox® Rail Mount comes with rail hangers. 6 screws, DIN rail, and a grounding bar are also included in each kit. Trusted Waterproofing: JayBox® Roof Mount utilizes QuickMount’s Elevated Water Seal Technology® that has passed the TAS-100 wind-driven rain test. Hassle-Free Lid: A detachable, hinged lid reduces interference—staying open and out of the way even on up to 70° roof slopes. Durable NORYL™ Resin: JayBox® is fabricated from SABIC’s NORYL™ resin, giving it greater strength and resistance to UV radiation. It is well known for its performance in extreme environments. Captive Hardware: Once the lid is closed, the single, pre-installed, captive screw and nut keeps it snug and secure. Drilling Guides: The enclosure has easy-to-drill guides on three sides of the box as well as inside for directing conduit from the attic.
