The knurled chrome handles are ergonomically contoured to fit comfortably in the users' palm. Smaller handles graduate up from 25MM grip to 35MM grip for increments 20LB through 125LB. The rubber coating increases durability, protects flooring and equipment, enhances appearance, diminishes noise and is easy to clean.
