R7000 Rails are high quality, fully welded support systems for rooftop unit noise reduction and seismic/wind restraint. R Series Rails can be supplied as individual rails in pairs or unitized. R Series Rails are ideal for supporting equipment that does not require a full perimeter curb or ductwork going through the roof. Each custom-built unit incorporates one complete structure. VMC engineers design each rail to custom fit any rooftop mechanical equipment.

R7000 Rails can be specified to compensate for large floor spans. Stanchions are positioned within the rail at the correct load points for proper support and seismic restraint.

Fully flashable rooftop rail support system also saves the contractor unnecessary labor costs. The rail and rooftop unit can be fully installed before the roof is sealed, eliminating the possibility of any damage to a finished roof. 

R Series Rails are fabricated from force-resisting structural steel specifically designed to withstand seismic and high wind forces. Unlike standard curbs that typically come with a rooftop handling unit, or sheet metal rails incorporating a seismic isolator, the VMC rooftop support systems combine our seismic design within a moment resisting frame. Our high strength frame is capable of direct, positive attachment to both the building structure and the roof mounted equipment while each stanchion provides seismic and wind restraint. Standard sheet metal rails that typically come with rooftop equipment are not capable of resisting these forces and do not allow for direct, positive attachment to the roof structure and mechanical equipment. Our high strength frame can be bolted or welded to the roof's structural steel and will not break away during an earthquake or high wind forces.
