Installation Overview
III.I QBox Location
Locate the QBox during the system design process to ensure optimal placement and compliance to permit
requirements. The QBox can be installed at any convenient location on the roof since it is designed for direct
securement to the roof's sheathing. It is acceptable to install the QBox under a PV module as long as the maximum
rated ambient temperature of the QBox will not be exceeded. To service the PV system, it is important to have access
to the QBox after the installation. When installing the QBox under a module, consider placing it under the last module
in a string or under a module that is easy to lift out of position for access.
The QBox utilizes a patented waterproof pass-through for ¾" EMT to run system wires through the roof into the attic.
If you run your wires through the attic, place the QBox in an optimal location for access when working inside the attic
space. In addition, do not install the QBox directly over a rafter such that the rafter interferes with the conduit coming
down from the QBox.
Installing the QBox into the sheathing does not require a pilot hole.
However, if an attachment screw for the QBox is to be installed into a
rafter, a 7/32" pilot hole is required.
WARNING: These products are NOT designed for and should NOT be used to anchor fall protection equipment.
