Unfortunately there is no barrier 34" or taller that is capable of being exactly 50" wide. The 34' high, free standing barrier is 55' at it's shortest width and the 36" high, free standing barrier is 54" at it's shortest. You could use either one but have the side support pieces outside the opening. If you look closely at the pictures of both barriers you will see an example of how that would work. That would make the barrier stick out into the area outside your opening about 10-17".
