Part Q and PAS24:2012/16 compliant, the Premiline Pro patio door from Kommerling features a highly innovative and high security locking mechanism operated through a patented interlock shootbolt system.

This delivers enhanced security without the use of interlocking bolts or exterior security measures, leaving sightlines uninterrupted.

High quality stainless steel tracks guarantee the maximum possible service life and smooth running, while the clean sightlines of the 70mm outer frame are further enhanced through a wide choice of colours and low sightline black or grey gaskets.
