Four versions of these opening rods are available: One-piece, i.e. non-separable, as well as a four-piece kit consisting of four different rods which can be combined with each other. All versions include an opening wedge. The advantage of the one-piece version is its robust lengthwise stability combined with a special field-tested moulding. With the four-piece version on the other hand you are more flexible and can react to several demands (door opening, opening engine bonnet etc.).
