Adapter for corrugated EL-pipes

Adapter developed for corrugated electrical pipes, that are to be installed through walls and ceiling beams. Developed to quickly and easily move the corrugated electric pipe through the pre-drilled hole. The method also has the advantage of not running the risk of getting any rubbish in the hose at he bushing.

* Use the adapter with the drill in the drill before drilling starts.
* After drilling through the wall, remove the drill.
* Attach the corrugated outer pipe hose and inner pipe so that the hose can be easily passed through the wall.
