Sash Weights
If windows aren't opening and closing with ease or are sagging the way they should, a malfunctioning counter-balancing system may be to blame. This could be due to a missing or damaged chain/sash cord, an unattached or misaligned sash weight, or a damaged pulley.
The sashweights are small boxes made of cast-iron that balance the counter-weight system and support the sash.
