## Questions & Answers

**Q: What is the depth of this vent?**
A: Maybe an inch or so

**Q: Why this is not good for pvc pipe ?**
A: PVC pipe does not have the same dimensions. Also, the knobs on the side are made for wood and do not always allow for a good fit. If you want to install one of these on a PVC duct for a furnace I suggest a termination vent like this - https://ventmastersstore.com/collections/pvc-termination-vents/products/3-round-pvc-termination-vent

**Q: Does this fit into the end of the exterior 3" pvc furnace vent pipes?  [as does "raven tvs3ss 3" vent pvc termination screen" product]**
A: Manufacturer states not for PVC.

**Q: What is the net free ventilation area?**
A: Pie X Radius minus 12% for the screen.
So...3.146 X 1.5 = 7.07 inches of area, -12% = 6.22".

Net size of the hole is 6.22". (or there abouts)

### ⭐⭐⭐⭐⭐ Good quality
*by P***. on September 19, 2025*

Perfect fit for a 3” pvc pipe, I used it for ventilating a crawl space

### ⭐⭐⭐⭐⭐ used these inside my sailboat's cowl vents as an insect screen
*by G***K on March 19, 2024*

Used two of these inside my boat's cowl vents. They have worked great to keep you the mud dauber wasps that love to nest in my boat. fit perfectly inside my 23.5" cowl vents. Yeah not the originally desinged application, but it works great as installed.

### ⭐⭐⭐⭐ Keeps the critters out
*by B***S on January 6, 2023*

Lightweight but strong, used in a camper van conversion when installing a vent through the floor. These were the perfect answer to keep out bugs and any mice that may be attracted to the hole. Fit into the 3" hole was good, but in my application, required the addition of sealant to keep it in place. Rating would have been 5 stars, but the shipping container (white plastic envelope) allowed two of the screens to be damaged. Perhaps even a lightweight cardboard box would have prevented this.
