Green Link has engineered a KnuckleHead 12 inch base, Big Base, designed to enhance the stability of larger rooftop-installed equipment. As with the standard universal base, the big base can be loose laid or attached.
The design features the standard universal KnuckleHead base in the center of a larger polyurethane base featuring a 12-inch diameter and 113.1 square inches of surface area. The standard universal base features a 7-inch diameter and 38.5 square inches of surface area.
Four holes at the center of the universal base extend through the larger polymeric base allowing for attachment to the roof. Attachment involving the Big Base results in a secure installation because it combines the benefits of a larger footprint with the additional security of four screws secured in the roof deck. Green Link Adhesive/ Sealant adheres to the base for further strengthening and sealing the installation.
