I see this a lot too.
I just had new kitchen cabinets installed and there is now a dedicated spot for the refrigerator. The spec sheet states the unit is 35 3/4" wide, which it is at the top and bottom. The sides are over 36" wide and the unit does not fit in the opening.
How big is the opening?
I see so many new houses that make the opening for the refrigerator the same size as the refrigerator itself.
For example if the specs on the refrigerator say 35 3/4" they will make the opening 35 3/4" and then wonder why it does not fit worth a darn.
Or better yet they will put the refrigerator in the corner of the kitchen and the wall next to the refrigerator will extend past the front of the refrigerator interfering with the opening of the door.
But I have seen refrigerators that fit fine when I installed them in new houses and years later when I need to pull them out to do repairs they were a tight fit.
