3" Day/Night Solar Vent
New design threads into included deck plate, and is
removable from outside without tools. On/off fan switch, LED lights and
intake/exhaust switch accessible from inside the cabin for ease of use.
** These vents have been designed to fit the same size hole
cut-outs as older model 3 and 4 snap-in Nicro Day&Night 2000 vents. Simply
remove the 3 or 4 snap-in deck plate from your older vent and replace it with
the 3 or 4 base plate from the new unit.
