There are no metal supports on the 301 card table. Also before buying a 301 check to see if the table is for a long bed 301 or a short bed 301. I thought the tables were only for the long bed 301 but I saw someone saying they had 1 for the short bed 301.
I am lucky enough to have 2 card tables one - for my long bed 301 and 1 for my featherweight. Unfortunately I have to wait for my kids to head back to college to have room to set them both up at the same time.
