There aren't that many places that utilize fire-rated horizontal assemblies. Is that what you are penetrating? Don't need the T-rating for a regular fire-rated floor if the pipe is not in direct contact with combustibles. See 8.3.5.1.4 of NFPA 101 2009 edition.

(Gov't project) They referenced the UFC 2-1.1 which then sends you to NFPA 101. Basically we need a T-rating of 1 hour. Has anyone had this before if so....which brand fire stop did you use?
