Exterior Conduit Drop:
The QBox can be used to transition to a conduit drop on the exterior of the building. Blocking must rst
be installed to the roof overhang below the location where the QBox will be mounted. The QBox conduit
nipple will pass through both the roof and blocking and the QBox lag bolts will secure into the blocking.
Once blocking has been installed in the proper position, install the QBox as per instructions on Page 7
of this manual. Pilot holes must be drilled through the roof and into the blocking for the QBox lag bolts.
Depending on the roof stack up, the lag bolts might shine through the blocking. Use washers under the lag
bolt head to raise it so they do not shine through to the underside of the blocking.
Building wiring strapping:
Per the NEC, wire or conduit must be secured within 12" of leaving the QBox conduit nipple. (EMT can be 3')
