Top LockAn automatic pool cover provides cleaner water, increased heat-retaining capacity and, above all, a safer environment: important technical features in equipment when the pool is closed.

In order to guarantee absolute security, T&A has developed a 100% automatic locking and unlocking system.


Opening and closing the pool cover is a simple operation thanks to the Top'Lock system. Optimal security is ensured at all times without the inconvenience of any manual operation. The system provides genuine active security and greater peace of mind.

Top’Lock is the only automatic system to comply with the French NF P 90-308 standard. It can be installed when building the pool with parts being positioned and sealed at the end of the pool. Top Lock is simple to install and easy to use, and its settings are programmed using automatic limit switches.

With over 17 years’ experience in the field of pool covers, the specialist T&A manufactures more than 2,000 covers per year that are distributed all over Europe and even further afield.
