Window spring balancer replacements are the perfect solution.
A sash balance or sash support balance counterbalances the weight of your sash window. Makes raising and lowering the window easy
in addition to helping hold it in place when the window is open. A channel balance, sometimes referred to as a side load
or a block and tackle balance, is a type of sash support balance.
We have included the most popular channel sash support balances available here for convenient online ordering.
They are the most common balancers utilized for (non-tilting) vinyl and aluminum single hung windows.
You will need the part number (usually stamped on the sheet metal housing of the balance) of your existing sash support balances.
Compare the top and bottom balance end brackets to the images below to determine the end bracket configuration.
The two most popular combinations are style "A" and style "B". There are subtle differences so it is important to
compare your end brackets to our drawings carefully. A good example of this would be to look at the "A" style bottom
end and compare that to the "B" style bottom and you will see tabs or wings on the "B" style that are not part of the "A" style end.
Each package includes the balancer, top and bottom end brackets (pre-attached) along with installation instructions.
To order here online simply click on the part number on the chart. The part numbers are composed of your existing
balance number and end style code.
When replacing a broken sash balance we recommend replacing both sides at same time to insure synchronized counterbalance.
Each order includes the all of the parts you will need for one side.
They are easy to replace regardless of sash window application.
