## Questions & Answers

**Q: What is the thickness of this? I need these to stick on vents that are on the ceiling and want to make sure they are strong enough magnets.**
A: Hello Relenned,

Thank you for asking that question. The XFasten Magnetic Vent Cover is 1/8" thick each. Moreover, yes, they are specially manufactured for ceiling applications and other places where downward gravity pull force is the strongest. As long as your vent has a full metal build, then these magnetic covers will mount strongly.

We hope that we were able to answer your question. If you have any other inquiries, then please don't hesitate to reach out to us through our Amazon storefront. Thank you and have a beautiful day ahead!

**Q: will it work on 10 inch round vent with opening of about 8 inches.  it is not flat**
A: not sure.  My take, try it and if not return.  I used it on flat 6X10 and works great.

**Q: can these be used on the outside of a shed in the winter to block cold wind?**
A: Hello Donna L Kirk,

Thank you for asking that question. Yes, indeed. As long as the area where you would be attaching the Magnetic Vent Cover in the shed has a full metal build frame, then it should work perfectly well. However, if the winds are strong, then we would recommend using the Neodymium Magnetic Base to reinforce the magnetic flux of the vent cover. These bases are made of neodymium magnets which can hold up to 70 lbs of mass, perfect for resisting extreme cold drafts. You can find the magnetic bases on the link below:

**Q: What is the size of each sheet**
A: Hello Trish T,

Thank you for asking that question. The XFasten Magnetic Vent Cover's dimensions are 8-Inch x 17-Inch. You can put two sheets if your vent is large and you can also cut it quickly using a sharp cutter or scissors if you need to trim the size down. Overall, it has a great magnetic flux for full metal build vents.

We hope that we were able to answer your question. If you have any other inquiries, then please don't hesitate to reach out to us through our Amazon storefront. Thank you and have a beautiful day ahead!
