02
Firestop is a tested system, not a caulk
The UL system names the manufacturer, the product, the thickness, the opening, and the penetrant. Get one of those wrong and the assembly is not rated, whatever the tube says. Send us the penetration and the rating and we will find the system.
03
Which yard carries which line
STI at Glenwood Springs and Eagle. Metacaulk at Grand Junction, Montrose, and Durango. If the system on your drawing is written around the other line, say so before you order.

What is SpecSeal?+
STI's main firestop product line. Sealants, collars, putty, and the systems built around them.
Do you stock enough for a whole building?+
Tell the branch the job and the schedule. Firestop goes in over months, not in one day, and we would rather stage it than have it sit on your site.
