MDF Series for Springless Sectional Doors

Find out About our Operator with Integrated Safety Catch

Springless sectional doors achieve high cycle rates while keeping maintenance costs low. Since there are no torsion springs to maintain or replace, they are a popular solution for areas where doors need to be opened and closed very frequently. 

Do you require a safe operator solution for your springless sectional door? If so, find out more about our MDF series now! Our direct-mount operators offer a TÜV-certified, integrated, and maintenance-free safety catch. What this means for you: You do not need to take any additional mechanical safety precautions when installing your sectional door operator!
