Only in two very small ways. 1) The flap on the end is slightly narrower, about 1 1/8" instead of 1 1/4", and 2) the rib-lock is located at 18 1/4" from the flap end instead of 18 1/4". Both are 8 1/2" wide. Actually, there was a mis-communication somewhere along the line and the 7X17" walnuts holders we currently have in stock and are seling have a flap end like the older holders, i.e. 1 1/4".
