Submit product data and samples of each type and color of window treatment. Provide slat samples 6 inch in length for each color.

2.1.1 Horizontal Blinds

Provide horizontal blinds with 1 inch slats. Blind units must be capable of nominally 180 degree partial tilting operation and full-height raising.
