Jumbo Collars


Ryanfire SL-X  Jumbo Fire Collars are designed to maintain the fire resistance of fire rated floors. The SL collars consist of a high quality stainless steel case lined with a highly reactive graphite infused material. These collars are designed to seal large bore combustible pipes. Upon exposure to heat the Jumbo SL collar will quickly and effectively close any openings that may form due to the melting away of services. 

For Specific applications, design and installation instructions are detailed on the relevant “V” Drawing.
