• Glynn-Johnson 410 Series Hold-Open Medium Duty Concealed

*Actual product and finish may vary

The Glynn-Johnson 410 Series Hold-Open Medium Duty Door Holder is for single or double acting doors – interior.

The best door control device is one that operates overhead, with an arm functioning from the jamb to the top of the door. When the door stopping or hold-open does not exceed 110°, this device is by far the most efficient.

The overhead holder and stop is out of the way, in contrast with floor or wall-mounted stops, which can be a stumbling hazard and are vulnerable to damage by accident and vandalism.

Glynn-Johnson overhead holders and stops should always be used on doors furnished with door closers, as closers are not door stops and should not be expected to perform that function. Glynn-Johnson overhead stops are designed to protect door closers from violent openings.

Glynn-Johnson catalog

Glynn-Johnson offers the most complete line of overhead door holders and stops, offering solutions for the most complex door control problems. The 410 series offers the industry’s widest variety of functions, base materials and finishes to fit all medium to light-duty applications.

The perfect combination of form and function, Glynn-Johnson 410 series holders and stops offer effective door control and a low-profile design. Each model is constructed so that the channel is encased in the door and the jamb bracket is mortised in the frame. When the door is open, the arm and jamb bracket are visible. Conversely, when the door is in the closed position, the entire holder is completely concealed.

These versatile models can be used with most surface-applied door closers. The provided templates allow for variable mounting positions, ranging from 85º to 110º of opening. These templates are designed for installation in almost all types of doors, including doors with conventional butt-type hinges or specialty hinges.

Models:

Glynn-Johnson 410 series holders and stops are designed for medium- to light-duty applications. They’re ideal for openings that are subject to normal activity, providing protection for the door, frame, hinges and surrounding walls or obstructions. All models incorporate the popular channel/slide-arm design and offset jamb brackets. This improved design allows for simple field modification of functions, should user requirements change.

410H Series Hold-Open:

(Suffix H) Hold-Open models provide a convenient method of holding the door open at a predetermined position for short or long periods of time, permitting an unobstructed traffic flow. The Hold-Open tension can be adjusted using an allen wrench through the end of the slider located in the channel mounted in the top of the door.

These models feature a rugged, automatic Hold-Open mechanism activated when the door is opened to a preset angle. Each model meets the 250,000 test cycles required for Grade 1 classification. The Hold-Open feature is not selectable, so the door is always held open.

Application Information

UL Classification:

The 410 series Stop-Only models are classified by Underwriters Laboratories (UL) as Miscellaneous Fire Door Accessories. This classification applies to use on either Hollow Metal Fire Doors or Wood Fire Doors. Where Wood Door manufacturer’s listing allows for the cutout required for installation, concealed overhead stops may be used on those wood fire doors. These units may be used on doors of any rating. As a reminder, the Miscellaneous Fire Door

Accessories (GVUX) section is defined by UL as: “Miscellaneous fire door accessories are intended in the individual Listings. The accessories have been investigated to determine that when installed in accordance with the manufacturer’s instructions, the accessories do not adversely affect the fire rating of the fire door and/or fire door frames.”

Dead Stop Templating:

Dead-Stop Templating is recommended for applications where a wall or similar obstruction is in place at an opening angle of 110º or less (i.e., doors that open back-to-back). Dead-Stop Templating can be applied to Hold-Open, Stop-Only and Friction models. The Dead-Stop position is the point at which the shock-absorbing spring is fully compressed. Therefore, when Dead-Stop Templating is used, the initial degree of opening will be 5º to 7º less than the Dead-Stop opening.

Example: If the holder is templated to a 100º dead stop, the door will hold open at an angle between 93º and 95º but no further than 100º.

Note: Do not use dead-stop templating on the 410SE Series since there is no shock-absorbing spring.

Environmental Considerations:

Environmental factors should always be considered when specifying overhead holders and stops. Doors that are positioned on a building’s exterior or subject to corrosive conditions should be equipped with a holder constructed primarily of stainless steel or brass materials. For interior applications, steel is acceptable, though brass substrates generally provide a more attractive architectural-grade finish.

Heavy-Use Applications:

A heavy-duty holder or stop should be considered when doors and frames are subject to heavy, frequent use. Also, heavy-duty units should be considered on exterior doors subject to wind.

Mounting:

Concealed overhead door holder installation requires that the jamb bracket be mortised flush with the bottom of the jamb. The arm and channel must be mortised into the door so the arm is flush with top of the door. A cutout made for the arm on the stop side of single acting doors as in the sketch. Double acting doors require a cutout for the arm on both sides of the door as shown in the sketch. Hollow metal doors must be reinforced at the top of the door to provide necessary strength for the channel. Hollow metal frames must be reinforced in the jamb to provide strength for the jamb bracket. Strength of wood frame and door must be adequate for the holder specified. Accurate template drawings for each holder give complete reinforcement and mortising specifications. They are readily available from your Glynn-Johnson representative.

Options

Suffix SOC (Pin-in-Socket Security Screw Package):

A screw package with pin-in-socket screws for mounting the jamb bracket to the frame is provided instead of the standard screw package.
