Excel Direct, Horizontal Termination, 4"

Horizontal terminations have been tested in high-wind circumstances and have proven to be reliable even in winds of up to 40 mph. The length between the terminations is a slip section that allows for wall modification. Built-in vinyl siding standoffs for siding up to 1½" deep are included with all Horizontal Terminations. An extra Vinyl Siding Standoff (VSS) is required for deeper siding.
