Very handy and perfect for box fans.
"I have one of these box fans holders in each of my horses stalls. They are wide and sturdy enough that they totally support the fan so you don't have to worry about any vibration moving the fan. The best part is they don't block air flow like hanging fan "nets" do. Need ALL the moving air here in hot, humid north Florida. My fans are on timers and the boys can come and go from their stalls and they love their fans."
