The carrier has a vertical portion including a first slot, a first projection extending outwardly from a first side of the vertical portion, and a second attachment projection extending outwardly from a second side of the vertical portion. The first slot receives a pivot bar of the tilt-in window via a vertical drop-in installation. One of the first and second attachment protrusions engages the first portion of the spring. The horizontal portion includes an aperture rotatably engaging a cam between a first position and a second position. The cam has a second slot aligned with the first slot when the cam is in the first position allowing for the pivot bar to move between the first slot and the second slot.
