High-resistance steel door reinforcement — anti-drilling, anti-cutting, anti-levering. Multipoint locks certified A2P (1 to 3 stars). Acoustic and thermal insulation.

The Shasama Fermetures door reinforcement transforms your existing door into a genuine shield. You keep the exterior appearance of your door while adding a high-resistance steel plate on the inside — maximum security invisible from the stairwell. Our steel plates prevent drilling, cutting and above all levering with a crowbar (80% of burglars enter through the door). Reinforcement is nothing without a lock to match: we install multipoint locks (3, 5 or 7 points) certified to A2P 1-, 2- and 3-star levels (CNPP). Adding a steel plate and perimeter seals considerably reduces hallway noise and draughts. Three solutions available: the Pivot Reinforcement, the Sheath Reinforcement and the Super Reinforcement.
High-resistance steel plate available in various finishes to preserve the desired appearance of your door.
