Cable Coating, Foam & Accessories
The supporting cast that makes firestop installs fast, correct and inspection-ready. C70 industrial cable coating protects grouped cables in trays — spray or brush applied, in gray or white — the standard for utility, industrial and data-center cable protection.
Blaze Foam fills basic penetrations fast; Draft-Block aerosol handles residential draft and smoke stopping. Denver Foam backer rod sets the right sealant depth in joints (a code requirement most failed inspections trace back to), and professional sausage and cartridge guns dispense 20.2 oz sausages — the format that cuts sealant cost per foot by a third versus tubes.
Remember: buy a pallet of any 20.2 oz sausage sealant and two applicator guns are included free, automatically, at checkout.

What does cable tray coating do?
C70 forms an intumescent, fire-retardant jacket over grouped cables so a cable fire cannot propagate along the tray. It is spray- or brush-applied, water-based, and standard practice in industrial plants, utilities and data centers.
Why do I need backer rod with firestop sealant?
Backer rod controls sealant depth and gives the correct width-to-depth ratio the UL system requires — too deep wastes sealant, too shallow fails. It is the cheapest insurance on the job.
Is the applicator gun really free with a pallet?
Yes — every pallet of a 20.2 oz sausage sealant automatically includes two professional applicator guns free at checkout. No code needed.
