This non-tilt block and tackle channel balance is constructed of a mill-finished steel U-frame housing. The internal working components include a spring, cord and pulley system, but the plastic top and bottom guide shoes must be selected separately as they are not included with the balance itself. These window counter balances are used to counter-weight the moving sash on single and double hung vinyl windows. If your windows (sashes), are having problems staying up when opened, it may be that your sash balances or hardware needs to be replaced. The sash balances hold the weight of the window pane, over time, the springs can wear out or fail. Replace your sash balance for a smoother operation of your window and allow fresh air to enter your home with a window that stays open.

  • Universal Compatibility: Can be used on most single or double hung windows
  • Durable Spring Construction: Heat treated high tension steel spring for long-lasting performance
  • Weight Capacity: Will offset the weight of a window between 14 and 17 pounds
  • Aluminum Channel Housing: Features a 5/8 inch aluminum channel housing for reliable operation
  • Installation Guide: Compare old guide ends and note their dimensions to order the new guide ends
  • Block and Tackle System: Non-tilt channel balance with internal spring, cord and pulley system for smooth window operation
  • Replacement Solution: Designed to replace worn or failed sash balances that prevent windows from staying open properly
