When fully extended, will accommodate materials up to 16' in length. An adjustable flip stop can travel the entire length of the extension, even when fully expanded, providing accurate measurements. A crown support provides additional support for taller materials up to 5-5/8". The legs of the extension can be removed for compact transportation. The extensions are primarily made from extruded aluminum and weigh 18 pounds each. The extensions attach to the Kapex's crown stops (494369), sold separately.
