Unscrew the sash stops (a thin vertical strip of wood that is used to hold the sash) and loosen any painted-covered hardware. Pull the sash to reveal the balancing weight, which is a heavy lead or iron cylinder enclosed inside a hidden compartment and anchored by rope. To prevent the sash from falling into the void, make a hole in it using nails and remove the weight.
