The Fortress IBL is a mechanical interlock blocking device that prevents machine restart before the operator has exited the hazardous area. It works alongside an existing safety interlock and requires the operator to remove a personal key, ensuring the machine cannot be restarted until the key is returned.
✅ IBL-H and IBL-S: models for hinged and sliding doors, left/right-handed versions
✅ Mechanical operation: no electrical wiring or programming required
✅ Prevents door closure: protects the operator while inside the machine
