Denali Industrial Supply can support all your fire stop needs.  We have STI (Specified Technologies Inc) certified trainers at both of our branches (Fairbanks and Anchorage).  We can provide you with installer training and furnish installer cards and certificates.  We can work with you on creating a submittal packet you can turn into a government agency for the fire stopping requirements on your job.   We regularly help customers find UL rated systems for applications on job sites.  If a UL rated system is not available for a situation on a job site we can submit the paperwork for an Engineering Judgement. 
For information on STI products, data sheets and UL rated systems visit STI’s website:
