Abstract
A breakaway sash lug assembly for a hung window includes a sash mount seat attachable to a window sash and a lug body rigidly attached to the sash mount seat via a releasable coupling that is configured to release at least one side of the lug body from the sash mount seat upon application a relatively small external force on the lug body. The releasable coupling may inhibit damage from inadvertent contact between the lug body and other portions of the hung window, for example during tilting of the sash for cleaning. The releasable coupling may include a hinge and a latch and/or a snap attachment.
