•	The power of a door closer should relate to the width and weight of the door onto which it is to be fitted. The chart opposite providesa guide to selecting the appropriate product.
•	Closers are designed to specific strength i.e.'fixed' strength or variable strengths whereby the power is either'adjustable' within the mechanism itself or 'selectable'via a temlate.
•	When fitting a closer in a parallel arm installation(app. 66),it is usual to experince some power loss and a stronger unit may be needed. However, some EUROART closers retain their strength regardless of application.
•	Certain environmental factors could impacton the opening force of thedoor,e.g wind pressures. if unusally windy or draughty conditions are expected,selected,select the power size for the next door width.

Applications

Backchek

Backcheck offers resistance to opening between 70° and 90° when the door is opened with excessive force. useful in all situations. Helps prevent damage to building and door frames, particularly where opening is resticted. NOTE: Backchek is not a subtitute for door stops which should be fitted whereever posssible.

Dyedela Action

Delayed Action slows down the closing speed of the door between approx 90° and 65°.The amount of delay can be adjusted and deactivated altogether.Ideally suited for applications, such as care homes, where people need a greater length of time to exit doorways
