Glynn-Johnson 70H Hold-Open models provide 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.

Glynn-Johnson offers a complete line of overhead holders and stops, providing solutions for the most complex door control problems. Glynn-Johnson 70 series surface-mounted holders are designed to meet the demands of high-traffic industrial applications. 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 butt-type hinges or specialty hinges. Glynn-Johnson 70 series holders 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.
