Product Introduction

The three-panel assembly places two moving glazed leaves on parallel paths beside a single sidelite. A mechanical telescopic linkage coordinates their travel, allowing the leaves to overlap as the entrance opens. The supporting header spans between the jambs and carries the sliding components. Trackless or pin-guide arrangements are available, with fixed or breakout sidelites determining the final movement pattern. A grasp handle provides direct manual operation without an automatic drive.
