This ruler rack is discounted due to a crack that formed during final assembly. The crack has been filled with CA glue that is used regularly for just this purpose. There is no structural issue in the ruler rack. I commonly use this glue as knot filler on many racks and it is a common woodworking practice. This is not a place of stress on the rack and no further issues should present themselves. If there is a structural issue with this please let us know and we will make it right.
