Technical Data
 Product Description
Nelson’s Fire Collar is a factory pre-fabricated firestop
collar utilizing our UL Classified Wrap Strip (WRS3™)

and CPVC combustible pipe penetrations in fire rated
walls and floors. When exposed to fire, the wrap strip
expands and forms a hard char to seal off the
penetrating item and preventing the passage of fire and
hot gasses.
 Features
