Abstract: A door control device for use on a non-fire side of a fire-door mounted in a door frame in a fire-door safety installation has a door closer assembly filled with a hydraulic damping fluid and attached to a non-fire side of the fire-door by at least one fastener; a door control arm pivotally connected to the door frame at a first end and to the door closer assembly at a second end; and the hydraulic damping fluid is one of a group of fire resistant hydraulic fluids.

Abstract: A self-trimming shield for the gap between a hinged door heel and its casing, includes a unitary strip of length approximately equal to the height of the door and made up of a sequentially arrayed plurality of elongated parallel panels. Opposite end panels of the plurality are attached, respectively, to the door and casing on the side opposite the hinge, while inner panels of said plurality are articulably connected with the end panels and with each other in such manner that, when the door is closed, the panels automatically fold to lie in close proximity to the door so that the shield appears to be an integral part of the door trim.
