A handle comprising: a first member, wherein a length of the first member is adjustable; and a bar extendably coupled between a non-extendable portion and an extendable portion of the first member; wherein a cavity is defined within a portion of at least one of the non-extendable portion and the extendable portion, and wherein the bar is enclosed within the cavity when the first member is in a non-extended position and the bar is extended from the cavity between the non-extendable portion and the extendable portion when the first member is in an extended position; wherein the handle further comprises an extension mechanism operably engaged with the non-extendable portion, the extendable portion, and the bar, wherein the extension mechanism is configured to extend the bar between the non-extendable portion and the extendable portion when the first member is in the extended position and retract the bar within the cavity when the first member is in the non-extended position; wherein the handle further comprises a second rotatable member configured to engage a door latch mechanism, wherein the second rotatable member is mechanically engaged with the first member; characterized in that: the extension mechanism includes a spring pin and a button operably coupled to the spring pin, and wherein activation of the button and the spring pin allows the bar to adjust the first member between the extended position and the non-extended position; the button is operably coupled to a lever mechanism and the spring pin engages with a plurality of notches defined along the bar, and wherein activation of the button causes the lever mechanism to disengage the spring pin from the plurality of notches to allow the bar to adjust the first member between the extended position and the non-extended position; and the button is further coupled to a first magnet and the spring pin is coupled to a second magnet, and wherein activation of the button causes the lever mechanism to adjacently position the first magnet and the second magnet such that the first and second magnets are attracted towards each other to disengage the spring pin from the plurality of notches to allow the bar to adjust the first member between the extended position and the non-extended position. a first member, wherein a length of the first member is adjustable;
