The Right Way

Loose-laid wood blocks used as support for pipes may deteriorate and rot from weather conditions or bacterial attack. KnuckleHeads are molded from weatherproof reinforced nylon and will not deteriorate from freeze-thaw cycles, UV exposure, moisture, or biological attack.

Solar KnuckleHeads are engineered to accept standard strut framing to create 15-degree angled structures for solar energy collection.

Lighten It Up

Sometimes concrete blocks are used to keep piping and struts elevated. Concrete adds considerable weight to the roof surface, forming depressions that allow water to collect, causing leaks. KnuckleHeads are lightweight and add little to the total roof load.

KnuckleHead

Paver Support

Paver KnuckleHeads are engineered to support a wide range of applications such as range plaza decks, ballast, access flooring, and walkways.

Height extensions up to 18” are available.

High and Dry

Codes may require pipes, conduit, ductwork and related equipment to be elevated to specific heights. KnuckleHeads can be height-adjusted by rotating the head. For larger increases in height, KnuckleHead extensions of 8”, 12”, and 18” inches are available.  KnuckleHead extensions are not height adjustable.

KnuckleHead

Extensions

In heavy snowfall areas, or where codes apply, a Universal Base Extension can elevate Knuckleheads by 8”, 12” or 18” off the roof surface.
