Installation Guide

Assembly of the Strongback

The new Strongback extrusion has been designed to accommodate a wide range of

PV Module sizes and configurations. As such, its flexible design requires special

positioning of the Rail Brackets to the Strongback to match the particular hole

placement of any given module. These instructions walk you through the proper

positioning and installation of the Rail Brackets.

The Strongback is shipped partially assembled with the Pivot Plates, Support Bar,

and the Mounting Tab for the Support Bar attached to the Strongback.

The Rail Brackets are bolted to the Strongback using 3/8” x 7/8” Track Bolts and

Flange Nuts. The Rail Brackets must be carefully positioned along the Strongback to

ensure proper alignment to the mounting holes of the PV Modules used in your

particular installation. To assist in this positioning, see publication

which lists various PV Modules and their

respective measurements to properly position the Rail Brackets along the

Strongback. Locate the PV Module to be used in your installation and use the

corresponding measurements “A” and “B” to install the Rail Brackets.
