The rods are manufactured in two types, namely the lockfast type and the universal type. The lockfast type has the advantage that it can be rotated in both directions with out coming loose just like the springsteel rods. The rods are not as strong as the spring steel rods and are not suitable for heavy duty work. However in the case of domestic drains these rods provide an ideal solution, combining light weight and flexibility.

Universal rods offer the same advantages as the lockfast rods but also have the advantage of being cheaper. If you are in need of "do it yourself" products then these are what you need. The main disadvantage with universal rods is that they come apart if rotated in the wrong direction.
