Nice product however, I emailed the company to ask which size door would fit an opening measuring 28 5/8.  I was told the 28, so I bought it.  Now that I have it hung, I have a 1/8" gap between the two magnetic strips and I am not sure what to do about it.  I was under the assumption that since the company said the 28 inch door would work, Id be good to go.   Other than that and the clunky installation instructions, the door itself is great.
