Perfect!!  We have cinderblock walls on one of our windows, so we had to trade out the wood screws enclosed.  But they are very high quality, the color is more of a taupe.  Again...  perfect!!  Love that they are cordless & glide up & down very easily.  I will definitely be purchasing more!!  Ordered on Friday received them on Thursday the following week.  Ordered 1/2" smaller than actual measurement of inside mount.  Perfect!!
