Ryanfire SL Collar

Ryanfire SL Retrofit Fire Collars consist of a high quality stainless steel case lined with a highly reactive graphite infused material.
Upon exposure to heat the SL collar will quickly and effectively close any openings that may form due to the melting away of services.
Ryanfire SL collars have a handy slim line profile providing a low clearance around services on which they are installed.
