The rail-free ballast flat roof mount system is suitable for commercial rooftops, a south-oriented racking solution for mounting framed modules on flat roofs with 5°, 10°mounting tilts. 

Variable ballast weight allows for local wind rating requirements to be met on individual basis. 

Eliminating rails equate to just few boxes per system, without the inconvenience of long, cumbersome rails. 

The simple and straightforward installation process of the system can save time and reduce labor cost.
