Quelfire QRS Intumescent Fire Sleeve for Ventilation Ducts
Quelfire QRS is a pressed-steel intumescent sleeve for approved plastic ventilation ducts passing through fire-rated walls. Its graphite core expands as the duct softens, helping close the penetration without a separate surface-mounted collar.
