How many do I need?

Round eave vents are usually in groups of 4, and occur every 8 feet of roof line.  As a data point, a two story house built in 2004 has 128 soffit holes.. 

Fit guide (below the calculator)

• Hole size: measure straight across. CinderStop fits holes about 1-7/8" to 2".
• Depth: look inside with a flashlight. You need at least 1-1/2" before any existing screen or blocking.
• Material: wood, fiber cement or stucco-faced trim all work. The cup grips the side of the hole.
• Existing screens: leave them in place. CinderStop seats in front of them.

How to install

About a minute per hole. One tool, no cutting.  See video: Installing CinderStop in a 2" eave vent.

Before you start

• A sturdy ladder, and someone to steady it
• Gloves: cut stainless wire ends are sharp
• Safety glasses for working overhead
• A soft brush to clear webs and dust from the holes

Steps

1. Clean the hole. Brush out webs and debris so the cup seats fully.
2. Start the cup. Hold the CinderStop with the open end facing into the hole and the flat black face toward you. Push it in by hand until it starts to grip.
3. Seat it with the tool. Put the tool's round face on the cup and push straight in until the tool's shoulder sits flat against the trim. That sets every cup at the same depth.
4. Check it. The face should sit evenly about 5/32" inside the hole, with no gap at the edge. If it tilted, pull it out and try again.
5. Repeat. Most people do a full wall in under 15 minutes.

Removing a cup: Hook the rim with a bent wire or small pick and pull straight out. Cups can be reused if they aren't bent.

Once a year: Look for webs or dust buildup and brush the face clean. A clogged screen reduces attic airflow.

Safety note (small print): Work from a stable ladder on level ground. If you're not comfortable working overhead, a handyman or a local volunteer program can install CinderStop for you.
