Vertical Opening Separation

Exit enclosures extend vertically through the interior of multi-story buildings in order to ensure timely and safe evacuation of occupants during an emergency. These enclosures include exit stairs and exit ramps.

An absence of stacking space dictated use of a unique McKEON product to seal this exit enclosure. The side coiling assembly requires a small box-like space, projecting the 3-hour steel curtain with conventional egress door along a very narrow pocket entry point and header slot path. When deployed, complete compliance with shaft enclosure opening protective requirements is achieved.
