Abstract
A fire-rated fitting includes conduit members forming passageways for wires to extend through an opening in a fire-rated floor. The fitting includes intumescent material which expands under heat to form a fire barrier. A top plate is provided on the fitting, the plate being easily detachable from and attachable to the fitting. The top plate can form a template for marking the locations of mounting holes. The fitting with the top plate attached is then firmly mounted in a non-rotatable fashion in the floor opening by using threaded fasteners through the top plate to attach it to the floor.
