FULLY HYDRAULIC CONTROLS
Maximum control over the doors closing speed is provided by the easy to operate hydraulic adjustment, whilst the versatile hydraulic mechanism also allows for 1st and 2nd closing (as illustrated), ensuring a smooth and independent control over the doors movement. The added benefit of a latching speed control is available with the COU-50 series and CO-55,56,whilst for the heavy duty CO-55 and 56 a new,adjustable,hydraulic backcheck function is a significant feature.
NEW MECHANICAL BACKCHECK FUNCTION
Available for all models in the series, the new mechanical backcheck (cushion check) function, features setting and adjustment
in the guide rail. The cushioned rubber absorbs the power of the door in the event of it violently swinging open, as in the case of
high winds or public misuse.

By the positioning of stopper, stop metal fitting (hold open device), and mechanical backcheck device, the door stop angle, hold open angle and backcheck angle are adjustable as required. Hold open force is also adjustable by the hold open force adjustment nut as shown in the chart.
