Neodymium Rare Earth Magnet 12mm x 3mm 10 Pack

Neodymium Rare Earth Magnet 10 Pack. 12mm wide x 3mm deep or (1/2" x 1/8")

While not required for standard steel 6" duct vents, these magnets provide extra assurance that your magnetic covers will stay in place and tightly seal any leaky duct work in your attic even with attic air leaks. 

Typically only 1-4 would be used with each vent diffuser. Vent diffusers from the Big Box stores typically could use 8mm. Contractor grade diffusers are usually slightly slimmer so an additional 3 or 5mm magnet is perfect.  

This pack includes:

Qty. - 10  of the 12mm x 3mm or (1/2" x 1/8")

Again these are not required for typical mounting. These are not replacement magnets for the vent covers themselves. Rare Earth magnets included with covers are permanently attached. These are for the center support only if desired. 

Giving you multiple options to confidently secure your vents.

Note: You do not want the center magnet fully connected to the center magnet in the vent cover, if you do this will prevent the seal surface making full contact with your vent diffuser. Use only if needed to help with non-standard mounting. We buy and resell these so if you find them cheaper elsewhere just make sure your using quality Neodymium Rare Earth magnets for best results.
