Hi, I have a situation where new fire doors were fitted to elderly tenants flats with Perko's. The doors were too heavy for the tenants, so the Perko's where disconnected from the frame and an overhead free swing device was fitted (In some cases the Perko has been removed completely). Once the door is closed, there is still a gap between the frame and disconnected Perko which compromises the integrity of the fire door. I am looking for some advice on how to overcome this issue. Thanks
