I am preparing a show which will feature a number of large pano prints to be hung in a public space. Displaying long panos is a difficult problem. I narrowed my options to two: magnets or PosterHanger. I ordered one sample of the 72" PosterHanger, and decided I need look no further. This is a great product. Very easy to assemble. The look is great. Affordable. Once the show is done, storage is no problem. Highly recommended.
They offer black, gray, and silver. My wife would much prefer white for display in our home. PosterHanger says they are in development on a white version, but that the silver may be painted. I may give it a go.
