Hold-Open model provides a selective Hold-Open function with easy-to-adjust tension. A simple 90 Degree rotation of the roller mechanism disables the Hold-Open function, allowing the unit to serve as a shock-absorbing stop. The Hold-Open function provides a convenient method of holding the door open at a predetermined position for short or long periods of time, permitting an unobstructed traffic flow through the opening.

The Hold-Open tension is simply adjusted incrementally for increased or decreased holding power by turning the nut at the end of the bar
