ABSTRACT:
A door latch operator for retracting a door latch comprises a handle having upper and lower end portions formed with front faces attachable to a door and a vertical hand grip portion between the upper and lower end portions. The upper end portion is in the form of a hollow housing having a chamber therein. The hand grip portion is in the form of a generally U-shaped channel which communicates at one end with the interior of the housing. A lever for operating the door latch is pivoted in the housing and extends into the channel in the hand grip portion to a position where it may be squeezed and rotated from a withdrawn position to a latch retracting position by a hand on the hand grip portion. The handle and the lever are both solid brass forgings.
