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.
