KnuckleHead

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 Type 1 glass-reinforced nylon resin, they are lightweight, UV-stable, non-corrosive, non-conductive, and highly durable. Solar Knuckleheads accept a 15/8 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.

  • Designed to accept standard strut framing to create 15 degree angled structures for solar energy collection
  • 2” to 3” adjustable height from base to support point
  • Base designed for adhesive attachment or mechanical fastening for seismic/wind uplift specification
  • Each KnuckleHead is able to support up to 600 lbs.
  • Molded from GREEN LINK Type 1 glass-reinforced nylon resin.
  • Strong, tough, weatherproof, impervious to freeze-thaw cycles
  • Matte-finish nylon allows bonding with adhesive

Important points about The KnuckleHead Support System

Solar KnuckleHead KnuckleHeads will prevent damage caused by ponding water, wind, ice, flying debris or seismic events and protect 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, a Halo Target Flashing can be applied. MB, EPDM, PVC, and TPO Halo Target Flashings are available from GREEN LINK. Flashings are heat welded and/or adhered to the KnuckleHead base and to the roofing membrane.

In some applications, GREEN LINK Adhesive/Sealant by itself is sufficient to create a strong bond with more than 250 psi shear strength to ensure KnuckleHead integrity under high wind conditions or seismic events. Pipe straps are available to provide additional security.

When mechanical fasteners are used, GREEN LINK Adhesive/Sealant should be applied around the perimeter of the TPO membrane knuckleheadbase and on each screw head to prevent roof leaks caused by penetration.

The base features 12 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 10 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.
