Holes drilled too small on part number 6 which is 3 pieces of wood, I requested new parts but they just sent another hardware bag instead of the parts that I requested. I had to buy a drill bit and drill larger holes on part number 6 in order to insert the cams (part F). There are also two sizes of cams provided with part F being smaller than part B. Part F goes into part 6 but it was still too big to fit without purchasing a drill bit to widen the holes. I would not recommend this brand to anyone as I was very specific about what part I needed-I included the pictures above-but they decided to send something completely different than what I requested.
