Wichard's Toe Rail Pad Eyes can be used on symmetric and asymmetric toe rails. They are designed to protect toe rails by spreading the load and eliminating nicks and dents. The unit can slide from hole to hole when it is partially unscrewed and can be removed when it is completely unscrewed. The Asymmetric Toe Rail pad eye has a collar length of 1 9/16 in. (40mm) and a safe working load of 2,650 pounds (1200kg) and a breaking load of 4,400 (2000kg). Made from 1/4 in. (6mm) eye stock, it is 1 in. (25mm) wide and 9/16 in. (14mm) high.
