It is a nice brackets (clips)for vertical blind. My blind is over 10yrs and I needed a few brackets to hold the valance. I couldn't find perfect fit. This is as close as the one I needed. I still had to use fire flame to vent to fit them. But it worked. I am happy now. But the price and shipping cost is too much for this little plastic parts.Was exactly what I needed. Fast shipping and delivery, too.Don't think I would have found these as easily as I did here on Amazon. Very pleased.These fit my blinds perfectly , thank you for the very good details and pics.All of the measurements were correct except for the depth of the clip on the head rail (which was not in the description). Was going to send back and get a refund, for the clips only (shipping not refunded). My husband was able to file the plastic wider to fit the head rail so now they are working fine. Lesson learned, only go for free shipping!Love that these are available! Didn’t want to have to buy all new blinds over a couple broken ones. Lifesaver!As long as you measure the dimensions of the old clips and the dimensions match these clips exactly you don't have to be concerned with numbers. They fit our blinds perfectly.they were what i needed, but fit a little tight, just hope they don't snap because of the extra pressure on them from being so tight
