Abstract

The present disclosure includes a handle assembly system for use with lift and slide doors. The handle assembly can include a handle housing that can serve as a support frame for housing and securing the handle flush within a front face of the door. The handle can be pivoted out of the handle housing and extended to increase length, wherein rotating the handle allows a user to actuate the door panels in order to open and close the sliding door system. The telescoping handle can allow a user to grip the handle and provide a lever-type function to reduce the force required by the user to actuate the panel, such as to lift the panel onto or off the track.
