In the same year that the Yom Kippur War breaks out, Avraham Bachri and Moshe Dolev invent the Rav Bariach geometric door lock, the cylinders of which connect throughout the door frame. The Pladelet (Hebrew for “steel door”) was the first steel security door introduced to the market, and by 1978 was the bestselling steel door in Israel. Today RB-Doors has sold more than four million steel doors throughout the world.
