Is there any other listing, other than WW-S-0059, with a F and L rating? I have exhausted my searches and cannot find one, but need it, WW-S-0059 is not accepted by the State Fire Life Safety Officer because of it. Options?
Hello,
WWS0059 would be the correct listing. There is no L-rating on this system, as mentioned, but we certainly could provide you an Engineering Judgment (EJ) with an L-rating. An EJ is a custom detail showing your exact application with the firestop components required to maintain the stated ratings.
