Company Profile


Accurate Lock and Hardware began in 1960 in Stamford, Connecticut as a division of Accurate Tool and Die, manufacturing specialty locks as a sub-contractor for Yale and Towne. Interestingly, Accurate Tool and Die was founded and operated by the lead foreman of the tool & die department of Yale & Towne, the one-time largest manufacturer of locks and hardware that was founded in Stamford in 1868. When Yale & Towne left Stamford for Tennessee in 1960, Carmine Salvatore established Accurate Tool and Die, which eventually spawned the creation of Accurate Lock and Hardware.

In July of 1972, Accurate Lock and Hardware was founded as an independent lock manufacturer by Carmine and his son Ronald. From humble beginnings, the company has since evolved into the premier manufacturer of custom architectural hardware products. In the mid 1970’s Accurate developed and furnished institutional locks specifically designed to retrofit existing preparations yet function to meet new code requirements, most prevalently throughout the New York State Institutional System. The company’s location in Connecticut afforded it the opportunity for frequent visits to the New York State office of Mental Health and Hygiene in a collaborative effort to develop solutions for their unique requirements. In fact, in response to the infamous Attica Prison riot, Attica officials commissioned Accurate to manufacture custom, high security locks. Within the next few years, Accurate introduced a robust dead latch, followed by a narrow backset mortise lock.

In the early 1990’s Accurate began manufacturing its 9100 series mortise lock, which has become the lock of choice among OEM trim manufacturers. Since then, Accurate has expanded its product line to include interior mortise locks, pocket door locks with trim, custom pivot and Harmon hinges, and most recently, heavy duty screen door locks and trim.

In addition, Accurate has developed a dynamic niche for manufacturing custom strikes and plates in the residential and commercial industries as well as custom cover plates and wrap plates for the university and hotel retrofit markets. Large enough to handle significant quantities yet nimble enough to set up for smaller orders, Accurate is even capable of furnishing special strikes and plates within 48 hours.

All the while, Accurate has been manufacturing custom architectural hardware for historical restoration projects at some of the finest addresses in the world including the White House, Ellis Island, numerous state capitols, and the House of Commons in Canada. We are proud that these products, like all of our products, were made, continue to be made, and will always be made here in our factory in Stamford, CT. On a daily basis, Accurate sales people provide solutions to challenging hardware scenarios: from mounting an exit  device with decorative trim to furnishing a 36” backset mortise lock, rebuilding an ancient lock, or even refinishing existing hardware to a unique finish.  Accurate has built a reputation as a company eager to satisfy all of its customers’ needs.  Quite simply, we believe our customers deserve the very best in quality and service on every order, with no exceptions!
