GREEN LINK Engineering has increased support strength by 40 percent on its KnuckleHead universal base attachment in response to customer needs in areas with high winds, seismic activity and other environmental fluctuations that can effect rooftop installations.
Greenlink Engineering’s retooled KnuckleHead universal base now offers an improved attachment feature for more secure installations. The universal base attachment, which accepts a range of head designs, originally featured two holes for securing the base using screws that penetrate to the roof deck. The retooling now features four holes which allows for the doubling of mechanical fasteners. In laboratory tests, the four-fastener base installation increased support strength by 40 percent tested on a 12-inch strut Knucklehead configuration. No change has been made to the basic design of the base. The holes are still positioned in the center, and the base can also be further secured and sealed using Green Link Adhesive/Sealant. A range of head designs can be fastened to the universal base for supporting struts, large pipes, small pipes, solar panels and pavers. KnuckleHeads can be attached or loose laid, depending on local conditions and specifications.
