Product Description... * York applied an ingenious innovation to the standard multi-hole grip plate and developed the "ISO-Grip" Plate, clearly the most maneuverable, safest plate in the industry today * The industry’s answer to a 360 degree easy pick up plate is cleverly achieved by casting the hub thicker (no thicker than a standard flange plate) than the rim. The patient-pending, radical benefit of a thicker hub and a streamlined rim is the 'anti-pinch' nature of using these plates. * The high quality rubber casing improves durability and protects floors and equipment * The streamlined rim ensures a comfortable grip and enhanced maneuverability with the 3-grip design.
