Details: Glynn-Johnson 70 Series Heavy-Duty Overhead Holders & Stops

70 Series Heavy-Duty

Glynn Johnson offers a complete line of overhead holders and stops, providing solutions for the most complex door control problems. Glynn-Johnson 70 series and 79 series surface-mounted holders and stops are designed to meet the demands of high-traffic industrial applications. These units are simple to install.

Compatible with a variety of door closers, these models come with templates to allow for variable mounting positions, ranging from 85º to 110º 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 and 79 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.

70H And 79H Series Hold-Open Models

(Suffix H) Hold-Open models in both series 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.

Both series 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. 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.

70S And 79S Series Stop-Only Models

(Suffix S) 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.

Glynn-Johnson 70 series Hold-Open and Stop-Only models provide heavy-duty door protection. 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).

Suffix J (Angle Jamb Bracket):

An angle jamb bracket is available to convert standard models to hinge-side or flush transom mounting If ordered with unit add suffix J. If needed separately, order either 70J or 79J by finish needed.

Suffix Sb (Sex Bolt Mounting):

A package of 4 sex bolts provided with the 79 Series and a package of 2 sex bolts provided with the 70 Series.

Suffix Soc (Pin-In-Socket Security Screw):

A screw package with pin-in-socket screw for mounting both the door bracket and jamb bracket is provided instead of the standard screw package.

Materials And Finishes:

Glynn-Johnson 70 and 79 series models are constructed primarily of Brass and 300 series Stainless Steel substrates, with several components fabricated of Steel treated to resist corrosion. Models in the 70 series utilize a½"-diameter stainless steel bar, while the 79 series uses a¾" stainless steel bar.

The bar is always provided in US32D. The spring, washer and nut are provided in a clear zinc finish. The door bracket, jamb bracket and hook (for Hold-Open units) are available in the following finishes: US3, US4, US10, US10B, US26, US26D, SP4, SP10, SP28, SP313 and SPBLK.

Glynn-Johnson

Known throughout the industry as the "overhead door holder specialist," Glynn-Johnson has made its name with state-of-the-art manufacturing and technology. Delivering both superior quality and exceptional performance, Glynn-Johnson products are offered in a wide variety of popular finishes and configurations providing the flexibility needed to meet the most demanding door control applications.

Glynn Johnson recognizes that the best door control device is one that functions overhead. Commercial doors are much too heavy for door hinges, making the Glynn-Johnson 70 Series Heavy-Duty jamb and arm design the best solution for a company looking to secure their doors. Furthermore the overhead holder is out of the way, unlike floor or wall-mounted stops which are a tripping hazard and are open to accidents and easy vandalism.
