Pull the nail free with needle-nose pliers, then insert it back into the side channel. The knot should be tucked into the the hole and secure it using a nail set.

Install the staff beads and put them back in the sash. Be sure to leave slack in the cords to ensure the proper operation. Last but not least, put back the balances and counterweights. To lessen the chance of draughts, a small amount of decorators caulk may be placed between the staff bead and the box.

A sash window functions by compensating the weight of the glass with the help of weights that are passed through the pulley system. These weights, usually constructed of cast iron, are accessible via an access panel or pocket in the inner lining of the box.
