JayBox® Junction Box

Protect the Nest

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.

JayBox® is available in two options: Roof Mount and Rail Mount—so you can keep all of your solar wires nested and protected.

Hassle-Free Lid

A detachable, hinged lid reduces interference—staying open and out of the way even on up to 70° roof slopes.

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.
