Review on Witten Automatic Vent 315CBL Replacement by Brian Garrett

Revainrating 4 out of 5

Easy to install - HVAC

Well done. Ease of installation. Tip: The 4 set screws are easier to adjust if this is done before inserting the vent into the foundation cutout. Tighten the screws once the vent is in place. Put 6 pieces, took 30 minutes. 4 stars instead of 5 because the packaging is damaged. Thank you Witten.

Pros
  • Works automatically without electricity; opens at 70°F, closes at 40°F (approx)
Cons
  • Quick Guide
