ProBuild Holdings, the nation's largest pro dealer, has decided to close down some of its newly built facilities in the Pittsburgh area, as well as operations in Hagerstown, Md. 

An HCN confirmation of an internal memo by ProBuild CEO Rob Marchbank last week showed that the Denver-based pro dealer has revisited its decision to operate three brand new LBM facilities in the Pittsburgh region. 

An attempt to reach ProBuild for comment or explanation received no response.
