    Glynn Johnson 450 Series Overhead Door Holders and Stops are surface applied to provide reliable door control with minimal door and frame preparation for all medium to light duty applications. Product is available with an option of hold-open, stop only or friction hold-open and a wide array of finish options.

    Materials: 450 series models are constructed primarily of brass, 300 series stainless steel substrates or steel. Brass and Stainless steel offer the highest resistance to corrosion, however all the above base materials are suitable for normal interior use.

    Function: Hold-Open model: Provides a selective hold-open function with easy-to-adjust tension.  Simple 90 degree rotation of the roller mechanism disables the Hold-Open function, allowing the unit to serve as a shock-absorbing stop.  Hold-Open function provides a convenient method of holding the door open at a predetermined location for short or long periods of time, permitting an unobstructed traffic flow through the opening.

    Stop-Only model: Provides a reliable method of door control when the hold-open function is not a requirement.  Provides shock-absorbing capability and may be used on fire doors.

    Angle Jamb Bracket: Available to convert standard models to flush transom mounting. Affixes to standard jamb brackets.

    Classification: Stop only models are UL listed as miscellaneous fire door accessories. May be used on hollow metal fire doors or wood fire doors without adversely affecting the fire rating on the fire door and/or fire door frame. 

    Installation: Product is provided with templates to allow for variable mounting positions, ranging from 85 degrees to 110 degrees hold-open/stop angle.  Templates are designed for installation in almost all types of doors. See Installation Tab for complete installation instructions. 

    Additional Options: including angle jamb brackets, blade stop SHIM kit and pin-in-socket security screws can be ordered. Please contact us or call our office at 845-388-1300 for additional information.

    Notes:

    A. Hollow metal frames should be properly reinforced with a 3/16" (5) minimum thickness by 12" (305) minimum length plate.
    B. Hollow metal doors should be properly reinforced with a 3/16" (5) minimum thickness by 2 1/2" (64) minimum width plate.
    C. Stop only units are permitted on many fire door applications. However, mechanical hold-open devices that require manual release are not permitted for use on any fire door as outlined on NFPA80 or NFPA101. Contact Glynn-Johnson or your local representative for assistance.
    D. Dead Stop (DS) templating may be used on hold open friction and stop only models, but should not be used on "SE" models. The DS position is reached when the shock spring is fully compressed. When DS templating is used, the initial degree of stop will be 5" - 7" less than the DS opening. For use on doors opening back to back, against a wall or obstruction.

    450 Series Adjustments:

    Hold open tension adjustment (Hold-Open) unit only: Using a 5/32" ball-end allen wrench, turn screw inside "long" end of cam clockwise to decrease hold-open tension and counterclockwise to decrease hold-open tension and counterclockwise to increase hold-open tension. Tension set to minimum at factory.

    Friction tension adjustment (friction unit only) - Using a 3/32" allen wrench, turn screw shown clockwise to increase friction tension and turn counterclockwise to decrease the friction tension. Dimensions in () are in millimeters.

    Installation:

     Overhead holders or stops must be installed before closers:

    1. A. Determine the mounting being used from illustration below.
        B. Select mounting group number from the chart below. Most continuous hinges are grouped with 4 1/2" wide butt or 4 1/2" swing clear hinge.
        C. Using the mounting group number and the overhead holder or stop size and the degree of opening desired, find "A" & "B" dimensions from charts on pages 3, 4 and 5. For dead stop add 9/16" (14) to the "A" dimension from the chart. See note D for information about dead stop.

    2. A. Locate "B" dimension on the frame. Note that the "B" dimension is measured from the centerline of the hinge as shown.
        B. For metal frames, use a #21 drill and 10-32 tap in 4 places. For wood frames, drill 1/8" pilot hole in 4 places. Refer to left and right plan views for appropriate hole pattern.

    3. A. Locate "A" and "C" dimensions on the door. Note that the "A" dimension is measured from the centerline of the hinge as shown.
       B. Drill the 1/4" (6) diameter through holes down 7/8" (22) down from stop in two places. On the pull side of the door, drill 13/32" (10) diameter hole. 1 5/8" (41) deep for sex bolt. Mounting holes should be prepared in the field.

    4. A. Install jamb bracket on the stop.
        B. Install the channel on the door with the shock spring towards the hinge edge of the door.

    Note: Dimensions in () are millimeters.
