CAMSTOPPERCamstopper® is the world’s safest and fastest mechanical pipeline plug to install and retrieve.

South Yorkshire based ASP approached Optima to design a  drain stopper that was quicker and more efficient than the old fashioned wing-nut drain stopper.

Optima developed a patented cam operated device that is easy to install and can be retrieved with the use of a tool. This means that the operator doesn’t have to enter a manhole and manoeuvre to retrieve the Camstopper manually allowing it to be used easily in confined spaces.


A mixture of engineering and industrial design resulted in the successful product that is now sold all over the world. For more information click here.
