About Cobra® Exhaust Vent for Roof Ridge

The original Cobra® Ridge Vent, protecting millions of homes, comes on a mesh roll for fast and easy installation with no complicated fitting, wrapping, nail gun adapters, connectors, or end-plugs needed. Available in both hand nail and nail gun versions, its shingle-over design helps it blend into the ridge line.

  • Nails Included:  Includes Smart Nails™ for reliable hand nail installation or 1 3/4” (44.4 mm) coil nails for nail gun installation
  • Easy to Install:  Quick 3-step process on roof slopes between 2:12 and 20:12
  • Ridge Cap Compatible:  Options available for 10” (254 mm), 12” (305 mm), and 11.75" (298 mm) wide ridge cap shingles


NOTE: Always have a balanced ventilation system. In no case should the amount of exhaust ventilation at the ridge exceed the amount of soffit ventilation.
