- 70 series models are constructed primarily of brass and 300 series stainless steel substrates
- 70 series utilize a 13mm dia. stainless steel bar

- 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 a number of alternative plated and painted finishes(consult the sales office for details)
- 70H series hold open models (suffix H) 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 only.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 hold open tension is adjusted simply and incrementally for increased or decreased holding power by turning the nut at the end of the bar
- Dead stop templating is recommended for applications where a wall or similar obstruction is placed at an opening angle of 110º or less. Dead stop templating can be applied to hold open and stop only 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
