Split Options

PermaCast columns (except for recessed panels) can be split numerous ways to fit the needs of the home. It is important to note that once the column is split, there is no load bearing capacity for the column. There are two options for split kits: a non-flange split kit or a flange split kit. Reeb has access to do the “D” cut on the columns, all other cuts need to be factory ordered from HB&G.
