Amesbury Series 450 5/8" Channel Block & Tackle Window Balance

Shipping calculated at checkout.
  • The 450 Series is a standard block and tackle window balance for tilt applications.
  • 5/8" channel depth.
  • This balance is ordered based on the length and stamp. The stamp is located on the balance and is either pressed into the metal or printed on it. To measure the balance, measure only the metal channel. If the balance is not available, measure the height of the visible glass. This will be your length. Then remove and weigh your window sash on a bathroom scale and select your appropriate weight range. These measurements are crucial to the performance of the balance. Check out our guide on measuring block and tackle window balances for more info on how to measure your balances properly.
  • Balances are sold individually
  • Weight capacities are listed per pair of balances in pounds.
  • For optimal performance, we recommend replacing both balances at the same time.
