A Multi-T-Lock

What is the History of Mul-T-Lock and Ingersoll?

In 1973, Moshe Dolev and Avraham Bachri founded Mul-T-Lock, inspired after Bachri’s neighbour requested he build and install a secure door for him in 1972. After completing the project, Bachri discussed with Dolev about designing secure doors and the two worked together on their first multi-point locking system. They created a company based on this initial design named Rav-Bariach and in 1985 renamed the company to Mul-T-Lock.

Over the next 30 years, the company gained international recognition through patented locking and locking systems designs. ASSA-Abloy bought the company in 2000 but the original founders still manufacture high-security windows and doors for the company while sharing in the Mul-T-Lock logo.

Prior to its global recognition as a lock manufacturer, Ingersoll used to be a watch company in New York. Charles and Robert Ingersoll founded the company in the 1890s and became famous for the Ingersoll Dollar Watch, which sold over 40 million units. During WWI Ingersoll started making aviation locks and in 1944, J.W. Taylor invented the world famous Ten Lever Ingersoll Lock (the classic SC71). It is a testament to the original design that the product is a flagship locking solution, 70 years after the first launch.

Ingersoll Locks Limited officially started operations in 1949 and has led the design and production of innovative lock production. The Ingersoll SC71 is the most popular product used by London homes as more than just a lock but a personal statement of good taste and the highest regard for safety.
