As you surely know, one of the main issues in fire testing of doors is the deflection of the leaves.

Our hardware – CHEMOLLI FIREBOLT A2.0 – is specifically engineered to lock the leaf to the frame, safely activating only when a fire has spread. The CHEMOLLI FIREBOLT A2.0 is activated once the internal temperature reaches about 150°C and this behavior will be beneficial to overcome fire tests in accredited laboratories.

Our device will enhance the performance of your products, satisfying the requirements of different standards (EN, UL, BS…).
