Product Overview
70 Series Heavy-Duty Surface Overhead Door Holders/Stops
70H Series hold-open model
Glynn-Johnson 70 Series holders and stops offer rugged durability and ease of installation. The surface applied door and jamb brackets provide reliable door control, yet require minimal door and frame preparation.
Compatible with a variety of door closers, these models come with templates to allow for variable mounting positions, ranging from 85° to 110° hold-open/stop angle. These templates are designed for installation in almost all types of doors, including doors with conventional butttype hinges or specialty hinges.
70H Series hold-open model
(Suffix H) Hold-open models in both series provide a selective hold-open function with easy-to-adjust tension. A simple 90° 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 70 Series provides 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. While both series are designed for demanding applications, the 79 Series is recommended for extremely heavy or wide doors subject to violent or abusive conditions.
