Product Introduction

This operator combines a powered swing drive with a return spring inside a slim overhead housing. A robust arm connects the output shaft to the leaf, and the controller manages motion where pressure differences or heavier use affect operation. The hardware is intended for demanding automatic entrances. It differs from the springless model by retaining a mechanical return element and from compact retrofit units by its heavier-duty drive arrangement.
