Quick Installation

The InvisiGuard Razor elevator edge is designed to be compatible with modern and older cab doors. Our unique dovetail bracket design makes configuring the edge for mounting to side and center parting doors an easy task.

The edges feature a slim design of 12 mm, making installations in tight or narrow spaces much easier. For those looking to modernize their current elevator security system, the InvisiGuard Razor is a great option.

Maximum Protection

The InvisiGuard Razor features 32 LED light pairs. These light pairs create 154 cross scanning beams to form an infrared light net to catch an obstruction of any size. Door protection runs 25 mm up to 1,800 mm above the door sill and is compliant with EN 81-70 standards.  

Health Monitoring System and Power Supply

Each edge set includes a visual health monitoring systems. These monitoring systems indicate that the system is fully functional during an inspection. The light source and receiver array are interchangeable. The 5m-cables are made with a high-flex material and are fitted with watertight industrial strength M8 connectors. 

The universal power supply makes connecting the InvisiGuard Razor to any door controller and cab easy. The power supply adapts to AC or DC supply voltages from 20 volts to 265 volts. For maintenance, there is no need to remove the edge or open the power supply, and replacing the cable is simple. 


The InvisiGurad Razor elevator edges are tested for ruggedness and reliability before they ever leave the factory. Each of our edges is age tested, being powered on and powered off, for 72 hours. The extrusion made of clear-coated aluminum and the window of the health monitoring system is polycarbonate, and the brackets are made of PVC.  The InvisiGuard is IP65 certified, meaning they are dust-tight and waterproof.

Each TRI-TRONICS edge comes with a 3-year warranty for additional peace of mind.
