BEWARE! I purchased a 156" kit . No problem it comes with two bars and a joiner. Big Problem the The pre drilled holes that are on 16" centers start only 7 3/8" from the end of the bar. When you join the other bar you lose the 16" centers as they the start at 143/4". Contacted Homcer customer support. They were not helpful at all and just said that's the way it is. Ended up cutting an 1 1/4" shim and putting in the middle. I can't think of a poorer way to design things and then they don't even care.
