Rooftop Support System
The KnuckleHeads Rooftop Support system features a range of height-adjustable designs and extensions that protect roofs by keeping pipes, struts, HVAC equipment, solar arrays, ductwork, walkways, and cable trays elevated.

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.
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.
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 Rooftop Supports can be bonded directly to the single-ply roof membrane without the need for mechanical fasteners. GREEN LINK Adhesive/Sealant adheres to PVC, EPDM, Mod-Bit, and primed TPO membranes as well as to the nylon base of the KnuckleHead.
