Beech shoji screens to span 146" with 1 mm White Warlon and inlaid Japanese Cherry door pulls. Each shoji 50" x 80" x 1-3/8". All three shoji will slide to one side with wood upper tracking and Sugatsune floor tracking with door rollers. Pictures of the bottom door rollers below - they engage a 'V' shaped metal floor channel inlaid into the wood flooring.
Also below, Elvis stepped in for scale. He is 6 feet tall.
The metal spacer is needed as the rollers install in a groove routed in the bottom rail for joinery screw. The spacer ensures the roller is secure and flush with the bottom of the shoji door. Ed milled them specifically for this application.
