Assembly Instructions, Power Rail P14 (Version 2, Rev A)

About the product

The Power Rail top-clamping PV module 

mounting system is engineered to reduce in-

stallation costs and provide maximum strength 

for parallel-to-roof or tilt up mounting applica-

tions.
Designed with the professional PV solar in-

staller in mind, the top-clamping rails utilize a 

single tool with a revolutionary RAD™ Fasten-

er for faster bolt placement. The unique shape 

of the RAD provides an anti-rotation feature, 

locking the bolt in the proper orientation when 

installed. The high strength rigid rails also in-

clude an integral wiring channel for securing 

cables  and  providing  a  professional  finish. 

The Power Rail Mounting System features 

the industry’s broadest selection of mounting 

supports, designed for secure and water tight 

attachments to any roof style.
