Calvert Safe & Lock began as a family owned business in Derby CT, in 1972. In the last 30 years we have grown to become the largest supplier of high security locks and safes in the New England area. During this time our business has evolved but the principles we have built our business on have remained true. We have never lost sight of the fact that it's our personal service that has brought us to where we are today. Whether you're in the market for the latest in electronic access, security cameras, a master-keyed system, a safe, or require a single lock installation, a visit to Calvert Safe & Lock will provide you with all the products to suit your needs.
