Rails up to 7.5' will be shipped as a single, continuous rail.Rails exceeding 7.5' in length are split into two pieces.NOTE: The rails join either by interlocking to one another at a fastening point or via a rail connector piece. Unless specifically requested by the customer, all split rails will come as interlocking. The interlocking point will occur at a pre-drilled hole in the rail and secured in place with a lag bolt and washer during regular installation.
