Interlock approved

Fortress claims to be the only trapped key manufacturer to carry independent third party approval on its trapped key range of interlocks, for use up to SIL3/PLe, reinforcing its position as market leader.

TÜV SÜD has certified that the mGard range meets the interlocking requirements of the latest European safety standards, so customers can install mGard with peace of mind.

Trapped key interlocking is an ideal method of safeguarding machinery or potentially dangerous areas. The mGard range has a fail-safe design, undergoing an extensive FMEA (Failure Modes Effects Analysis) during its design stage, with over 100 different, rigorous safety tests.
