The Vator III series is unquestionably the most reliabile and best-built system available today. The 'core' of the VATOR III stands is the precision rack and pinion gear drive mechanism that reduces components within the drive train to only two moving parts. This will ensure years of reliable operation with minimal maintenance. Matthews has such great confidence in the new VATOR III stands that each stand is covered by a three year warranty under normal operating conditions. Excludes wheels and tires.
