Solar Support System
KnuckleHead Solar Supports provide critical benefits: 1) They protect low-slope commercial roofing systems from damage due to movement and excessive dead loads and 2) they prevent damage to the PV arrays resulting from wind uplift. Molded from GREEN LINK glass-reinforced nylon resin, they are lightweight, UV-stable, non-corrosive, non-conductive, and highly durable. Solar Knuckleheads accept a 1-5/8 inch (41.2 mm) wide framing profile. Front and rear supports are engineered to create 15 degree angled structures for solar energy collection. Each head also functions as an elbow connector which permanently fixtures perpendicular strut members in the same 15 degree plane. Each unit can support up to 600 lbs. of load.

Important points about The KnuckleHead Support System
KnuckleHeads will prevent damage caused by ponding water, wind, ice, and flying debris, protecting the integrity of the roofing system including roof-mounted structures and equipment.
They are engineered with a Universal Base. A range of head designs are available depending on the particular support application needed.
KnuckleHeads can be attached directly to the roof substrate either mechanically combined with GREEN LINK Adhesive/Sealant, or with GREEN LINK Adhesive/Sealant alone.
Where the protocols of the original single-ply membrane manufacturer and/or warranty provider must be met.
In some applications, GREEN LINK Adhesive/Sealant by itself is sufficient to create a strong bond with more than 275 psi shear strength to ensure KnuckleHead integrity under high wind conditions or seismic events.
When mechanical fasteners are used, GREEN LINK Adhesive/Sealant should be applied across the bottom of the base on each screw head to prevent roof leaks caused by penetrations. .
The base features 16 holes, allowing adhesive to squeeze out as the base is pressed onto the roof surface. This creates “adhesive rivets” which strengthen the bond.
KnuckleHead installations have been performing in the field for more than 20 years, with constant exposure to high temperatures, freeze-thaw cycles, UV exposure and stress, and they have shown no signs of deterioration.
GREEN LINK Adhesive/Sealant is environmentally safe and presents no toxic risk to contractors or building occupants. It is solvent-free, isocyanate-free, nonflammable and odorless.
A 10-year warranty is available. Please contact GREEN LINK for details.
