GUFERO eyed snap hooks are similar to eyeless ones. The main difference between these two types of snap hooks is the added eye which is intended for pulling through a rope. Due to this the snap hook does not rotate when disconnected or reconnected. Unfortunately, this type of snap hook is only available in the zinc plated version. The DIN 5299A standard is applicable to the manufacture of this type of snap hooks. Eyed snap hooks are available in the same dimensions as the eyeless snap hooks.
