(o.k. I know I'm going to regret asking this - but I have no shame) What provides the solid interior surface when a sleeve penetrates a block or stud wall? Mark A.

They also provide for a space between the pipe and wall for packing if necessary when providing certain UL listed penetrations at rated walls and partitions. Sleeves are at times a requirement in walls or floors of particular construction types in order to maintain the assembly's rating. UL details require sleeves for penetrations in many cases. ject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
