This is a an installation clip for your vertical blind. Fits rails where the top is approx. 1 1/2" or 1 9/16".These clips should be spaced apart no more than 32 inches. I also recommend adding an extra clip to the heavy end, installing it side by side, where all the weight is once you pull back your blinds. This will eliminate sagging and your keep your slats from touching the ground over time. Please note that the L bracket is not included in this purchase.
