Step 3
With the top of the new S775 channel balance fastened securely to the window track, carefully pull out the shoe approximately 8 inches. The shoe is attached to the block and tackle pully string at the base of the balance. You will feel resistance when you pull out the shoe.
Pulling the shoe out of the channel balance about 8 inches.
Step 4
Wrap the string around your finger to create slack on the string between your finger and the shoe. If the pressure is too much on your finger, use a pair of locking pliers instead. Warning: S775 balances made for heavier windows will have a great pull and it is a better idea to use locking pliers instead of your finger.
