Ken, I have not seen any response to your question so thought I would offer my opinion, I have seen them used in the past when a second layer of sheetrock was installed but I don't like using more than one per head, unless you calc them, I only know of one manufacturer that has a listed one, brass ones are better, it has to do bad things to the head K factor.

They are removing the existing clg and installing a new one 3" lower. Can I use 1/2" nipple extenders? If so what is the max length that can be used? 1"? 3"? -- _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum ----- No virus found in this message.
