Q. How do you set or lock it when in position at 110 degrees?
The angle of hold-open is freely selectable between 80° and 180°. There are no settings or adjustments; the door simply has to be opened past 80° and then released at whatever angle you require it to stay open. In the event of a fire or power outage the electro-hydraulic hold-open will release and the door will close. To manually close the door you only have to pull the door and the hold-open will release, allow the door to close automatically.
Q. Can you please explain the closing force rating 1-6 for door closers?
The closing force rating 1-6 relates to the maximum width and weights of fire door that the door closer is suitable for and if you click on the link below and then click on the EN size guide this gives the table with the closing force categories and the relevant maximum door widths and weights. http://www.safelincs.co.uk/Door-Closers/
