The counterweight is a device that helps the closing of the landing doors. This device replaces the safety spring installed on the landing doors and it keeps the closing force applied to the panels constant. Available for the central and side opening landing doors, this device is installed as a standard on the Sematic doors with big dimensions, and that have an increased panel weight. Pay Attention!
Regading the rules of the counterweight presence (one or two), and it's dimension, instead of the spring refer to the enclosed document
