Thank you. This was quite a challenge at the time when I designed it and had the contractor install (we have 3 of these groupings down a long hallway of the children's wing). It was customized using various components generally used in retail display. I've seen similar groupings that have used the stainless steel cables like you see on contemporary stair railings. This really helped to organize MANY photographs and not have the worry of a mix of different style frames, alignments, etc that one would normally be concerned with when hanging a grouping of photographs.
