Zenith Twist Shackle is suitable for connecting chain or rope to minimise twisting. This D-shackle features a twist in the loop 90° to the pin. Twist Shackles are commonly used for shade sails where the mounting eye is vertical and the shade sail ring is horizontal. Using a twist shackle keeps the shade sail in its flat plane. All parts are constructed from marine grade 316 stainless steel, offering superior quality and corrosive protection to perform in tough conditions including coastal environments.
