Since 1920, Razeto and Casareto have been designing and manufacturing locks and door accessories.
To mark 100 years in the industry, the company set out to usher in a revolution in the world of door handles and developed the Ossh, a door handle that does more than just open doors – it communicates with you too.
Relying on a patented cable-free power system, the Ossh door handles have LEDs inside them that illuminate to act as ‘signage’ of sorts.

Just simply by looking at a handle, you can tell if the door is locked or open, and the LED’s different colours can even transform into a wayfinding system, allowing you to color-code doors to let people know what’s on the other side or even help them during emergencies.
Moreover, the handles are also capable of self-sanitising, using a combination of purple LEDs and Esi – a permanent antimicrobial anodic protection coating.
Ossh is a multifunctional door handle system featuring a variety of safety and management applications. Lighting up in critical conditions Ossh can even help direct people to safe escape routes. Ossh is available in kits: Stand Alone, for privacy; Wired, for fire doors; and Wi-fi for domestic and commercial setups. Ossh even features Esi – an antivirus, antibacterial, and antifungal technology that uses silver ions for sanitation.
Tested and certified to kill coronavirus, the combination of Esi and the ultraviolet LEDs help sanitise the environment and the hand while opening the door.
The Ossh multifunctional door handle is a Silver Winner of the A’ Design Award for the year 2021.This locks and door accessories manufacturer needs to be in Nigeria this coming July for Africa’s biggest housing and construction event, the Abuja International Housing Show (AIHS).
The 15th edition of the annual event will be holding at the International Conference Centre from July 26 through 29.At the event, participants have the right to exhibit their products, and will be given spotlight on the media.
Convener of the AIHS, Festus Adebayo, says the annual event always welcomes innovations in the housing and construction sector like that of Razeto and Casareto.
