Frequently Asked Questions
- How weatherproof is the window donut for camper?
The EPDM accordion boot creates an airtight, watertight seal when installed correctly. It's designed to keep rain, dust, and wind out — ideal for camper conversions and pass-throughs.
- Can I install a window donut for camper in cold weather?
Yes, but it's best to warm the window donut for camper slightly beforehand. Cold temperatures may make the rubber less flexible and harder to manipulate during installation.
