KnuckleHead installations have been performing in the fieldfor more than 15 years with continual exposure to high temperatures, freeze-thaw cycles, UV exposure and stress, and they have shown no signs of deterioration.
KnuckleHeads prevent damage to the membrane caused by ponding water, wind, ice, flying debris or seismic events and protect the integrity of roof-mounted structures and equipment. GREEN LINK can custom cut metal strut, or design and manufacture special support elements such as this custom-molded base pad for a corrugated metal roof.
They are engineered with a Universal Base that can accomodate a range of head designs depending on the particular support application needed.
The Universal Base is designed with two holes at its center for accepting mechanical fasteners. Before penetrating the roof membrane, the contractor should consult with the manufacturer to ensure that the warranty is not voided.
