Be the first to review this product

Glynn Johnson 793H Hold-Open provide a selective Hold-Open function with easy-to-adjust tension. A simple 90º 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. 793H provide a durable Hold-Open mechanism that can be turned off, allowing the unit to function as a shock-absorbing stop. The Hold-Open tension is simply adjusted incrementally for increased or decreased holding power by turning the nut at the end of the bar. The 79 series models incorporate the basic characteristics of the 70 series, but can protect extremely heavy or large doors subject to violent use or abusive conditions (i.e., vault doors, cell doors, oversized plant entry doors).
