VSC75120, VSC15120, VSC1120 and VSC2120 are listed under OSFM 8165-2192:0501 as continuous vents.
The September 2025 handbook description gives VSC2120 2-by-120-inch dimensions, 24-gauge G90 galvanized perforated steel, 1/8-inch-diameter holes and a 3/4-inch flange. Beneath exterior #14 type 304 stainless ember mesh sits an intumescent-coated, 5-mm hexagonal aluminum core made from 0.05-mm foil.
Vulcan discourages galvanized steel in coastal settings or within 5 miles of the ocean because salt accelerates corrosion. Its recommended stainless steel, copper, powder coating or other suitable coatings applied before installation do not establish substitutions within this listing. Match the exact model and flange, including suffix differences.
The manufacturer recommends a bead of EverKem 814+ behind the nailing flange before installation. Its diagrams are conceptual: consult a licensed building professional for specific installation; ridge use belongs beneath a vented ridge cap. The handbook names ASTM E2886 and directs readers to manufacturer instructions and data sheets.

Vulcan’s Continuous Vents page (captured 2026-09-11) discourages galvanized steel in coastal environments or within 5 miles of the ocean because salt air accelerates corrosion and rust.
For those locations, Vulcan recommends stainless steel, copper, powder coating or other appropriate protective coatings before installation. These manufacturer options do not establish an alternative material as part of OSFM listing 8165-2192:0501.
For continuous-vent installation, Vulcan recommends EverKem 814+ intumescent caulking and says to run a bead behind the nailing flange before installation for an airtight vent-to-building seal. The page’s separate round-eave exception is not this continuous-vent model.
Vulcan labels its soffit and ridge diagrams conceptual; the application may vary and specific installation requires consulting a licensed building professional. In a ridge application the vent is designed beneath a vented ridge cap.
The manufacturer’s continuous-page table distinguishes base VSC2120 from flange-front VSC2120FF and other suffix variants. Match the exact listed model and flange configuration; a common width does not make every manufacturer variant part of listing 8165-2192:0501.
