410 Series Door Holder/Stop - Standard Duty Concealed
410 Series Door Holder/Stop - Standard Duty Concealed
General Features
The 410 series offers the industry’s widest variety of functions, base materials and finishes to fit all standard (medium) to light duty applications. The perfect combination of form and function, 410 series holders and stops offer effective door control and a low-profile design. Each model is constructed so that the channel is concealed in the top rail of the door with the jamb bracket morticed into the frame. When the door is closed the entire holder is concealed.
These versatile models can be used with almost all Relcross surface overhead door closers . Templates provide variable mounting positions allowing hold open and stop positions between 85° and 100°. 410 series holders and stops accommodate doors hung with conventional full mortice hinges, offset and centre hung pivot sets (consult sales office for more details).
Four distinct versions offer solutions as follows:
410H Series Hold Open Model – Standard Duty
Holding the door open at a pre-determined position for long or short periods. The hold open function is an automatic mechanism that ‘kicks-in’ when the door is opened to a preset angle.Tension is adjusted using an Allen key.
410S Series Stop Only Model – Standard Duty
Providing an effective ’out of the way’ auxiliary stop when the hold open function is not a requirement.
410F Series Friction Hold Open Model – Standard Duty
Used in situations where multiple hold open points are desirable. Friction tension is adjusted using an Allen key
410SE Series Special Stop-Only
Note: Caution should be taken when using this option in other applications, as the elimination of the shock-absorbing spring can put added stress on the door and frame.
Each model is available in five sizes as shown in the table in the 410 Series - Data Sheet (Part 1) on the next tab. 410 series hold open and stop only models provide standard duty door protection.
Materials and Finishes
All models are available in 300 series stainless steel, brass and steel substrates. Stock finishes include US32D satin stainless steel and SP28 powder coated silver.
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.
Note: Do not use dead-stop templating on the 410SE Series since there is no shock-absorbing spring.
Environmental Factors
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, brass or bronze materials. For interior applications, steel is acceptable, though brass and bronze 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.
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.
