Remove any security fittings in front of the lower window sash. Then, remove the staff bead. Finally, pull out the bottom sash.

Remove the sash stops (a thin vertical strip of wood that holds the sash) and remove any paint-encrusted hardware. Pull the sash to reveal the balancing weight, which is a heavy iron cylinder that is encased inside a hidden compartment and secured by a rope. To keep the sash from falling into the void, make a hole in it using nails and remove the weight.
