By choosing Fortress, our customers have complete peace of mind they have chosen the best possible protection for their employees. Every application is unique, so we offer every one of our customers a fully customised solution. We design around specific machine safety needs to guarantee the best safeguarding solution available.

We’ve come a long way since our first simple mechanical locks by fully embracing advances in technology and by working closely with our customers. We are highly innovative, incorporating technology as it becomes available to improve both safety and productivity.
