The header on this sample is screwed to the frame of the sample. So it is uneven on the sample. It does not come like this when assembled or being assembled.
The bumpers go on all 4 sides of the header which push it outwards to match the door below, which is also pushed outwards from the hinge and bumpers on the door (same distance).
Feel free to order every sample door that you are considering. As soon as you purchase your new kitchen from The RTA Store (and send us back the sample door(s) we will refund the money you spent on all sample doors (less shipping charges).
