The Proto II Wall system is the single most significant development in site and interior fencing. That's a bold statement to make, but when you consider what it brings to the table in benefits and cost savings, that it can allow the choice of a durable concrete masonry unit (cmu) wall in lieu of budget driven, non-durable wood fencing, that it is used by the majority of major builders, and that...well, you get the idea. It's a fencing solutions with serious up-side and broadbased acceptance.
And for very good reasons. Proto II incorporates cmu in a patented post tension structural principles and time tested engineering from other post tensioned systems. Proto II to be a superior system for site wall and common/privacy wall applications. It has redefined the way fence walls are built.
Savings and Advantages
Of course, tremendous savings would be a primary advantage for the builder, Proto II has saved builders very substantial dollars for years, it's also true that its better price buys a better wall.
