The RONDO Base is supplied ready-to-install with a stainless steel clamping strap.
If necessary, clean the outside of the pipe.

Push the RONDO Base onto the end of the pipe and slide along.

The RONDO Base should be mounted centrally on the wall/floor plate.
Always ensure a minimum concrete covering of 5 cm.
The distance to the surrounding reinforcement or other components must be at least 3 cm.

The clamping strap is tightened to approx. 5-6 Nm torque to prevent the RONDO Base from shifting during concreting.
During concreting, ensure thorough sealing around the RONDO Base in order to prevent defects/rock pockets.
