Glynn Johnson 704S-SP28

The Glynn Johnson 704S-SP28 is a heavy duty, surface mounted overhead door holder/stop equipped with a hold-open option. 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.

The 704S-SP28 provides 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 unit 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.

When the Hold-Open function is not a requirement, Stop-Only models provide a reliable method of door control. Stop-Only models provide the same shock-absorbing capability as Hold-Open models. The Stop-Only model may be used on fire doors.

The unit features a powder coat aluminum finish and is designed for door openings with a range of 33-1/16" to 39".
