This door closer is used on light to medium usage interior and exterior inswing doors up to 3/0 wide.
All Cal-Royal 700 series door closers are available is polished brass US3 and polished chrome US26 plates finishes with lead time. Add $65.00 each which includes the arm, cover, parallel bracket and screws. But this closer must be ordered by calling customer service.
This door closer does not include the parallel arm bracket required for push side applications where the door closer body is mounted on the door. Please be sure to order the #C705 bracket for applications as described above.
This door closer comes packaged with both wood and machine screws and does not include "sex" or thru bolts. These sex bolts, as they are commonly referred to, are necessary (and sometimes required) for mounting the closer body onto a door which is either not reinforced or properly blocked for a door closer.
For instance the proper method of attaching a door closer to a metal door would be to "drill & tap" the door and frame and then attach the door closer using machine screws. Sex bolts are necessary when the door has not been reinforced for a door closer because the face sheet of the steel door is simply not thick enough to "hold" the screws.
Additionally on wood doors it is not possible to attach the door closer to the door using screws when you are dealing with hollow core or fire rated mineral core doors. In the case on fire rated mineral core doors it is to be considered required to use sex bolts when installing the door closer.
Please note this closer is not handicap compliant nor intended for high usage or abusive applications. For these applications please consider viewing the related item as shown below.
