We’ll made gate with easy operation.  Installation requires mounting four ‘pads’ to the wall (with screws) to connect with bars extending from the gate structure.  The bars are not adjustable so the length of attachment is fixed.  Two bars are longer and equal in length facilitating mounting on an even, flush wall.  The third is half the length, presumably to mount on mounding or other surfaces not parallel to the other two.  Moving the three bars around the Stantion isn’t the easiest, but doable.
