Unison Door Controls satisfy a comprehensive range of applications from a light duty contract unit through to high performance architectural units suitable for the most prestigious of projects, all available in standard and metal finishes.
When selecting a door closer for your project particular attention should be paid to the choice of unit ensuring the correct power size, application and standard is selected. To assist with this selection process please refer to information and selector pages.
 Backcheck: Backcheck offers resistance to opening between 70º & 90º when the door is opened with excessive force. Useful in all situations, helps prevent damage to building and door frames particularly where opening is restricted.
 Delayed Action: Delayed action slows down the closing speed of the door between approx 90º and 70º. The amount of delay can be adjusted and de-activated altogether. Ideally suited for applications, such as care homes, where people need a greater length of time to exit door ways.
 Controlled Closing: All Unison door closers have an adjustment value which allows the closing speed to be controlled. This is effective throughout the whole closing cycle except where delayed action or latch action are activated.
 Latch Action: Latch action provides for the adjustment of the last 10º of closing (approx). This allows the closer to be adjusted to overcome a latch or intumescent seal.
Drop Plate: Most door closers can be supplied with a drop plate, which allows a door closer to be fitted where the top rail of the door is too narrow to allow normal fitting. The drop plate is first attached to the door and then the closer attached to the drop plate.
Stand Open/Hold Open Arms: These arms can be supplied for most door closers and when fitted will hold the door open at 90º. STAND OPEN/HOLD OPEN ARMS MUST NOT BE USED ON FIRE RESISTING DOORS. |
