Two Mounting Types

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.
