if you go the direction i have gone use the locking c clamps and have an eye welded onto the handle. if you adjust your spacing you can place the clamps so that they are positioned underneath the banner and you can't even see them. if you are committed to the size of the banner and it just doesnt measureout the same as the glass panels you may want to paint the clamps the same color as the metal dividers so that the clamps don't stick out like a sore thumb if it is going to be viewed from close distances..if it is viewed from any distance at all i wouldnt worry about it.
