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.

Lite Pipe Support

Lite Pipe KnuckleHeads are engineered to support a single 1” pipe or two 1⁄2” pipes for such applications as electrical conduit and condensation pipes.

Height extensions up to 18” are available.

LIGHTENING 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 total roof load.

Heavypipe-Knucklehead

KnuckleHead
Heavy Pipe Support

Heavy Pipe Knuckleheads are engineered to support large pipes up to 3” in diameter for such applications as natural gas and water pipelines.

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.

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.

PENETRATION FREE

KnuckleHeads can be bonded directly to the single ply roof membrane without the need for mechanical fasteners. M-1® Structural Adhesive/Sealant adheres to EPDM, Mod-Bit, and primed TPO membranes as well as to the nylon base of the KnuckleHead.

M-1® Structural Adhesive/Sealant

M-1 is a non-shrinking polyether adhesive/sealant specially formulated to bond the KnuckleHead base to the single-ply roof membrane. M-1 provides a waterproof seal and shear strength up to 400 psi.

KnuckleStraps, KnuckleCaps, KnuckleClips and KnucklePads

Where high winds or seismic events are present or where code requires it, pipes and struts can be secured in KnuckleHead rooftop supports with custom engineered straps or caps molded from tough, weatherproof urethane, tinted “safety yellow.” The slip resistant KnucklePads reduce movement and protect the roof membrane.
