The team at Unique Fire Stop have developed an interactive AHJ Preapproval app. on their website:
Why not have the firestop you have selected pre-approved by the inspector before you step foot on the job?
Use their convenient form to send your proposed fire stopping system specs to your AHJ (Authority Having Jurisdiction) for preapproval. Your System is approved when the Inspector says it is. Note that you will use one AHJ form for each UNIQUE firestop product you specify.
