Product Introduction

The integrated tensioning system keeps this tear-resistant PVC curtain under tension while it closes. A gearless drive transfers power through a chain, with the rolling sheet guided within a compact frame. The leading light barrier runs inside the door case and monitors the closing edge across its width before contact. A transparent viewing section can be selected to preserve sightlines through the curtain on indoor routes with limited installation space.
