Permanent Railing System Options

Post Weight System

Post Weight System

Post Weight System uprights are supported with weighted bases. This kind of base has a small footprint making it easier to fit the railing in tighter spaces. Post weights don’t stick out into the walking area reducing trip hazards. This system does require return sections of railing to anchor it in place.

Counterbalance System

Counterbalance System

With the counterbalance system, the railing uprights are supported by spreading the weight out. This reduces the weight strain on the roof. The counterbalance system does not require return sections of railing to anchor it in place.

Infill Panels

Infill Panels

Infill panels act as a fence by attaching to the top and bottom rail of the system. Only approved materials can be attached to the system due to wind loading requirements. Custom chain link and picket options are also available.

Integrated Toeboard

Integrated Toeboard

The base of the system is designed to connect to an extruded aluminum toeboard. This component of the railing is needed when there is no parapet to protection objects from falling over the edge of the rooftop.
