Balance Window Springs For Single and Double Hung windows.
Replacement window springs used on many single hung and double hung windows with compression tilt jamb jamb liners. Each spring will come with a Clip as shown in picture. Clip is removable if you do not need it on your window.
Due to the multiple sizes springs come in we do not stock springs. All springs are special order with a 1 - 2 week lead time. NO RETURNS for springs as they are special order/made to your order.
Spring is 3/8" Diameter outside to outside
The spring gauge or tension is as follows and is commonly associated with these color tips on the springs themselves: Red .041, Green .044, Yellow .047, Black .048, Purple .051
To Order By Spring Length Inches : Measure from tip of Eyelet to tip of Eyelet on spring. (Eyelet is the round bent out part of the spring located at both ends).
To know what color gauge and length to order you will need to remove the springs from the jamb liner. On Hurd windows the Springs are color coded at one end with paint. Please watch both how to videos below that show how to remove the jamb liners from your window/reinstall and how to remove and replace the springs.
Pro Tip: If the Springs are old and maybe a little stretched out it is better to order springs longer then you need as you can cut the springs shorter if needed by using a pair of Wire Cutters or Cable Cutters. Then you can bend out the eyelet with pair of regular pliers and flat head screw driver. See demonstration video below.
Lead Time: Due to the multiple sizes springs come in we do not stock springs. All springs are special order with a 1 - 2 week lead time. NO RETURNS for springs as they are special order/made to your order. Larger orders may have longer lead times. Please contact us with any questions.
Have been used on Hurd, BiltBest, Weather Sheild and Cradco windows and many other window brands.
