Green Link Introduces Knucklehead Stanchions and new Mechanical Support Products

KnuckleHeads are a height-adjustable rooftop support system featuring a range of designs and extensions that protect roofs by keeping pipes, struts, HVAC equipment, solar arrays, ductwork, walkways, and cable trays elevated. The KnuckleHead rooftop system contributes to longer lasting roofs and more efficient and sustainable construction.

When local building codes require that equipment such as air conditioning units and compressors be elevated off rooftops to allow snow and water accumulation to flow underneath, Green Link Engineering's Knucklehead Stanchions and new Mechanical Support Products are the solution.

The Stanchions feature a vertical slotted channel with an over-molded urethane footing, which is threaded and designed to mate to the center bolt of Green Link's Knucklehead Bases. Support rails can be set into the slots and secured with brackets to form a structural frame.

Installed, the stanchion allows equipment to be elevated from 6" to 24" off the roof or ground surface. Once the height is set, the channel slots allow support rails to be moderately adjusted so equipment can be optimally leveled. 

The Stanchions are sold separately or as part of the Elevated Mechanical Support Assembly kit offered by Green Link. The kit includes KnuckleHead Stanchions, support rails, equipment rails and necessary hardware for constructing 3'X4' or 4'X4' support frames. Custom lengths are available upon request.

triangular base with the strut channel incorporated,
which allows attachment of all standard strut

Pipe Clamps

Standard strut compatible metal clamps can be used to secure pipes of varying diameters. 

Standard size MetalHead is 9.5″ long and can carry multiple pipes simultaneously.

Polyurethane Insert

A molded polyurethane insert is engineered to slide into the channel top for securing up to seven .850″ pipes. 

The insert fastens to the head with standard bolts.

Elevated Channel

In this configuration, a section of channel is elevated by threaded steel rods, which attach into a threaded urethane block insert that slides into the MetalHead channel. 

This configuration elevates pipes up to 18″ off the roof surface.
