Installation Instructions:
Clamp Installation
– Portrait Orientation
End Clamp Installation
Mid Clamp Attachment
There must be a minimum of 1.5 inches of Rail
extending beyond the PV panel frame.
Clamp the PV panel frame by inserting the T-Bolt
into the Rail slot. Position the End Clamp firmly
against the PV panel frame and secure using the
1/4-
20 Collar Bolt. Using a 7/16” socket, torque to
7.5 ft. lbs.
Note: When two or more PV panels are installed
grounding via the End Clamp is optional. For a
single panel configuration (shown), insert the T-
Bolt into a T-Bolt Holder for grounding the panel to
the Rails.
Insert the T-Bolt in the Rail slot and turn
clockwise 90° to engage the head into the slot.
Insert Grounding T-Bolt Holder to lock T-Bolt in
place.
Thread the 1/4-20 Collar Bolt onto the top of the
T-Bolt as shown. After positioning the Mid
Clamp firmly against the PV panel frame, using
a 7/16” socket, tighten to 7.5 ft. lbs.
Proceed with the mounting of the PV panels
using the mid and end clamps. Specific
mounting instructions are shown in the following
sections for Portrait and Landscape mounting.
Installing Mid Clamps: A mid clamp is used
between PV panels. It will produce 1/2” spacing
between PV panel frames.
An End Clamp is used to secure PV panels at
the ends of a row.
