Drop In Fire Collar

  • Allproof Drop in fire collars provide a simple and effective passive fire rating option for thin concrete floors or trapezoidal steel tray concrete floors. These floors feature profile changes on the underside of the slab and make it difficult to fire rate with a conventional fire collar fixed to the underside of a floor slab.
