• About Us
SDP/SI deemed an essential business during the pandemic
2020 has been an extremely difficult and unprecedented time for all of us. When New York and other states were closing down due to the pandemic we remained open and operational, making the health and safety of our employees our primary concern.
Our ability to act quickly and adjust to this extremely fluid situation allowed us to focus on our many medical and military customers. Implementing proactive steps to limit disruption to delivery schedules we continued manufacturing key components for medical devices and healthcare equipment, including COVID-19 testing machines.
Our primary concern continues to be the health and safety of our employees, families, and partners. Preventive measures are in place as we continue to follow the recommendations and protocols from the CDC – Centers for Disease Control, state and local governments.
Established 1950, Stock Drive Products/Sterling Instrument (SDP/SI), a Designatronics brand, provides engineered mechanical solutions to the aerospace, medical, defense, robotics, recreational and commercial industries.
