The RAC-A-TAC Rolling Knee Pads are a breakthrough in professional workwear, specifically designed for auto body repair technicians, painters, fabricators, and similar professions. These knee pads are perfect for those who need swift lateral movement, especially on rough surfaces, and are ideal for individuals with large feet or long legs. The option to add a chest support transforms these knee pads into a versatile tool for easier tile laying, providing upper body support while keeping the lower body free for movement. The height adjustability from 11.5" to 15.5" ensures a perfect fit for various body sizes, while its lightweight design at 8 lbs supports up to 300 lbs without compromising mobility. The caster model enhances knee-based movement, making it quicker and easier. The web spring seat offers unparalleled comfort, eliminating the need to sit back on heels and allowing free movement of feet. The knee pads themselves are a standout feature, with thick foam padding for all-day comfort and a floating design that alleviates direct knee pressure. The polyurethane ball-bearing casters provide smooth rolling over dirty, wet, or dusty areas, elevating your body to eliminate pressure on toes, ankles, and knees. Additionally, the convenient tool tray ensures that your tools are always within reach. Made in the USA, the RAC-A-TAC Rolling Knee Pads are not just a tool but a testament to American craftsmanship, offering professionals an unmatched combination of comfort, efficiency, and mobility in their work.
