Abstract
An assembly of plastic louver strips secured by two vertical frames having cut out portions into which the louver strips extend. Louver strips which are flexible can be snapped into place after the frame is in place. Flexible strips can also be removed for cleaning. The vertical frames are slidably assembled into basic frame members and when in place form a space into which the ends of the louvers are positioned.
