Paver Support System
KnuckleHead Paver Supports are designed for a wide variety of mechanical support applications including plaza decks, ballast, access flooring, roof walkways and similar applications. Each KnuckleHead can support up to 600 lbs. KnuckleHead extensions are available for raising pavers to higher elevations up to 18”. Paver supports are lightweight, so they add little to total roof load, preventing low points and depressions that invite ponding water and ice build-up.
- Designed to support pavers, ballast stone and walkways
- 3.75” to 4.85” adjustable height from base to support point
- 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
- Base designed for adhesive attachment or mechanical fastening for seismic/wind uplift specification
Important points about The KnuckleHead Support System
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 base 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.
