How to install 3L TripleLock & Click4U

3L TripleLock®

3L TripleLock is the easiest and fastest system for flooring installation on the market. There are no inserts needed like other fold-down systems. The elimination of the additional insert on the short side provides manufacturers with the possibility to improve productivity levels as well as to reduce their costs and carbon footprint. The 3L TripleLock click system is suitable for existing high speed production. The system has multiple installation benefits: it is up to 30% faster than basic clicks, there’s no squeaking and no special tools are needed for installation.


An angle-system for the long side combined with 3L TripleLock on the short side. The angle system has proven itself for many years and combined with the drop-lock on the short side the locking strength is very high. Just like 3L TripleLock, Click4U is suitable for existing high speed production machinery. The system has multiple installation benefits as well. It is fast and easy to install and doesn’t require any special tools.
