The KB2407 builds on the robust foundation of the KB2403, adding a built-in pec deck attachment for targeted chest training. This versatile Smith Machine combines a 3x3 inch, 9-gauge steel frame with a guided barbell system and dual-pulley cables, offering a complete strength and isolation workout solution. Ideal for squats, bench presses, cable exercises, and now butterfly movements, the KB2407 is engineered for safety, adaptability, and professional-grade performance in home or commercial gyms.
