Product review (5 stars): MagVent - Great idea for dryer hose couplings.
After seeing a home video of this magnetic catch vent coupling on Facebook but no information about the company or name I decided to try looking on Amazon and found the name and website [...] and looked to see if they had other options than the one shown on Amazon. I have a mobile home with a floor vent and not very much room at all.  I needed just the magnets without the long stand up piece and found the magnet coupling with just the flange to strap the vent pipe coming out of the floor.  I ordered it from Mag Vent and got it today.  It was very easy to install, even for this 70 plus senior.  It had a plate that screws on the floor. Then I pulled up the vent pipe (very stiff aluminium) pushed it on the bottom of the magnet and strapped it tight on the magnets flange.  Then I took a one foot length of flexible vent pipe and attached it to the other half of the magnet.  When my new dryer arrives in a day or two I'll attach that half to the dryer vent coming off the dryer and then let the magnet catch.  It has a very strong catch.  I don't forsee any problems with lint or air escaping from  this device.  The best part is that it doesn't take up much room at all and I won't have extra vent pipe kinking or falling off  anymore. Also, if I want to pull the dryer out to mop the floor it will be super easy to just pull the magnet apart.  This company really should advertise more.
