Button joints

Wonkee Donkee Trigger Lock Joint on chimney and flue rods The button joint is a quick and easy way of joining fibreglass and nylon type rods, however, it is almost exclusive to nylon and fibreglass rods. This type of joint is most commonly used on power rods as the rods can be turned in either direction without coming apart.

Spring joints

Wonkee Donkee Spring Rod Joints used on drain rods and chimney rods Coiled spring drain rods are unique in the way they connect together. At one end of the rod, the spring coils are separated out (female joint) and at the other end they form a tight and narrow section (male joint). The male joint on one rod is screwed clockwise into a rod with a female joint in order to join the rods together to increase the length.
Wonkee Donkee Separation key for separating coiled spring drain rods from one another A separation key is required to disconnect the rods. This key fits over the exposed end of a rod and is then used to “open” the end of the spring slightly to allow unscrewing. Spring joints form a very strong connection but are difficult to clean and can be tricky to separate.

Steel rod joints

Wonkee Donkee Steel Rod Joint used on drain rods and chimney rods The method of joining steel drain rods is particularly secure. The male end of one rod attaches into the female joint of another rod and is secured by a retaining nut.

This type of joint is ideal when the rods are being used with power tools such as drills with a root cutter attachment fitted as the rods will not come apart accidentally and the joint is extremely strong.

If you have reached the point where you need to connect your rods to a power tool, Wonkee Donkee would advise you get a professional in to complete the job due to the damage that can be caused in such circumstances.

Which type of rod joint should you choose?

Wonkee Donkee Lockfast joint is undoubtedly the best joint available on a polypropylene drain or chimney rod The majority of joints are specific to the particular type of rod, so a steel rod has a particular type of joint, which is only available on a steel rod, as is the same with a coil spring, and button joint on a nylon rod etc.
