The majority of these pegs have large diameters on one side and a smaller diameter on the other, so it is crucial to take out the smaller-diameter sides first. Later sashes used glue instead of pins. They can be cut by using a knife or mallets.

Once the sash has been released, you can remove the sash stops and gain access to the weight pockets. This is usually done through tiny holes at the bottom of every jamb. The hole is then covered with the wooden panel which can be removed to reveal the inside workings.
