Yeah its a law to have USFS (United States Forestry Service) approved screen.. The law doesn't state that the housing of the screen has to be approved. and alba's screens are approved. They (DNR) dont make you have the stickers. Atleast not here. We talked to the Head DNR officer for about 2 hours on this. The screens we're using are 4 months old and still going with the season over.. so they lasted a year for us.
You can hate on Alba all you want, thats your choice. I dont buy anything from them either. But.. that 15.00 kit saves you alot of money over the big ass clamp on sparkies that can fall off (as his did) and get lost. If someone else made them, I'd buy from them. But as far as I know no one else does.
