Abstract
A tamper proof interlock insert for window balance carriers that is non-permanently installed into a drop-in carrier to prevent the unauthorized removal of the sash from the window frame. The interlock insert is inserted into the channel by the window manufacturer after the pivot bar, which connects to the sash, has been inserted into the carrier. Once the interlock insert is installed in the carrier, the pivot bar cannot be removed. Since the interlock insert is non-permanently installed in the carrier it can be disengaged from the carrier relatively easily by a trained technician in the event that the sash must be removed from the window for repair or replacement.
