Nystrom Universal Series Singe Door hoistway vents are rooftop venting systems for hoistways, elevator shafts, and stairwells that automatically opens, releasing heat, smoke, and noxious fumes during a fire. Reference IBC section 3004 for hoistway venting requirements.

Nystrom recently developed a new order guide and corresponding model numbering system to help you select and specify product options that meet your specific needs. We are currently updating all of our downloadable information with the new nomenclature but the process is not yet complete. We apologize for any inconvenience this may cause. Please do not hesitate to contact us with any questions or concerns.
