GREEN LINK Strut KnuckleHead Supports are designed for a wide variety of applications including air conditioning units, oversized pipes and other HVAC equipment that is to be installed on commercial roofs. GREEN LINK KnuckleHead Rooftop Strut Support System is designed to accommodate standard metal struts which can provide a framework for keeping equipment elevated off the roof’s surface. Each KnuckleHead can support up to 600 lbs. 


KnuckleHead extensions are available for raising roof-mounted pipes and equipment to higher elevations up to 18”. In areas where hurricanes or seismic activity are present, mechanical fastening is often required to secure installations. When mechanically fastening the strut into place, bolts or screws pass through the side of the head into the metal strut. A secure installation can be achieved without bolts or screws using GREEN LINK Adhesive/Sealant to bond to the metal channel as well as to the molded nylon surface of the KnuckleHead. With shear strength of up to 275 psi, GREEN LINK Adhesive/Sealant can replace mechanical fasteners making for easier installation.
