How big is a hairline crack?
sol400

Hi,

I have new manufactured, all wood cabinets and the mitered corners have gaps you can insert a dime into. Is this considered a hairline crack? The manufacturer is implying it is and referring me to Norm's article on painted cabinet hairline cracking.

I build furniture as a hobby and none of my joints look like these... but I also cannot build a room full of cabinets in 6-weeks. :-)

Thank you

A hairline crack is a failure without separation. Two boards in contact with each other but not glued together have a hairline crack between them. A porcelain mug that is cracked but hasn't fallen apart yet has a hairline crack. Cracks in concrete that are a result of shrinkage during curing are hairline cracks, as long as there is no movement involved.

What you describe is not a hairline crack; that's called a "gap" as a result of failure of the glue bond or horribly shoddy workmanship.

Fencepost pretty much covered it. You cannot insert a dime into a joint and call it a hairline crack.

Hairline cracks are just that, there is no perceptible gap between the two pieces in question. What you are describing is a split, gap, or crevice, one in which there is measurable distance between the pieces in question.

But if you can insert 9 cents, it's definitely not a hairline crack.

Thank you for the great replys. I always thought a hairline crack was the width if a hair but am getting an argument from the manufacturer and yes I think I can get 9 cents in some ;)

Now I can come back with opinions other than my own.

When I was building and installing cabinets in multi-million dollar homes, the standard I was held to was that a single-edge razor blade could not fit in anywhere. Not now and not 3 years from now until the 'cosmetic' part of the builders warranty had passed. And the cracks described here are not 'cosmetic' but 'structural' and excessive by any reasonable standard.

New cabinets for free are in order, but if they are built like these (which they probably will be) I'd be suing for a refund including demo, disposal, and installation labor costs so I could buy some decent cabinets from somebody else.
