I purchased two-piece aluminum DIN rails from Amazon to hold the two 64x64 Matrix displays together. These rails measure 12.9 inches in length, 35 mm in width, and 7.5 mm in height. However, since both displays are 10 inches, some parts of the rail are poked out from the sides. Alternatively, you can cut off the protruding parts of the rails.
I suggest purchasing a smaller DIN rail set, such as 9-10 inches, to comfortably fit the matrix displays and avoid cutting aluminum rails.
