An apparatus for opening a door 48 from a remote location including a lever assembly and a pulling line 22, the pulling cord 22 having attached thereto a door handle engagement means (60, fig.10), the lever assembly (20, fig.3) including at least a first guide (40, fig.3) and a second guide (42, fig.3) for guiding the pulling line 22 and a mounting means 24 for mounting the lever assembly to or adjacent a door 48. Pulling the rope 22 pulls on the handle down and the first and second guides are positioned such that when the pulling line 22 is prevented from moving through the first guide pulling on the pulling line acts to cause the lever assembly to apply a force to urge the door to open. This apparatus allows an operator to gradually open a door or to apply a suitable force if, for example, the door is stuck in the closed position and allows safe opening of a door from a distance in case it were to be booby trapped. The guide means may be pulleys mounted on an L-shape lever frame 26 and the mounting means 24 may be a telescopic support bar mounted between the jambs of a door frame.
