It consists of 2 louvers that are installed in the upper and lower air ducts. These 'flaps' can then be rotated up and thus shut off 50% of the air to the shoe and walkers. There are blanks that be placed on the louvers that can shut off 90% of the air. Upper and lower are adjusted separate as needed. This is for clovers, fescue and other light seeds.
