The Spring Cage Assembly is part of a heavy-duty, Grade 1 commercial door lock hardware system that is rated one of the best in the industry. The primary component of the original Spring Cage Assembly was an expensive zinc die casting. Quality issues stemmed from the original Spring Cage Assembly components that resulted in field complaints and a deteriorating reputation for this product in the marketplace.
Using the long list of quality concerns as a template, our APD group designed and developed an innovative product solution to address all shortcomings of the original system. With our new product, several additional features were incorporated with fewer components. A stronger, more durable lock set was the end result. There was a 7 fold improvement in cycle test performance and our customer was able to turn this one-time liability into one of the best performing product launches in company history. With improved quality, durability, UL Fire Code adherence, and savings in excess of $1,500,000, the product was a success, and Trans-Matic received supplier of the year award for the best “New Product Development” in 2003.
