Thanks for your patience. For your first question, concerning the screw length, if this is the first time these balances were replaced, the original screw should be the correct length. You commented that it seems too short. To prevent any damage to the sash, maybe go up just 1/8" or maybe even 1/4" to a longer screw. I would take the old screw to your local hardware store to get a longer one.
For your second question, screw in the top hole of the balance and use needle nose pliers to pull the cord out to give some play. Then, lock the cord with locking pliers. That will allow you to place the plug in the window jamb. Once that's in, release the cord slowly. These are under a lot of tension so you have to be careful, you don't want it to snap up. Since this is a particularly strong balance spring, I suggest having someone help you. |
