Window broken

Hello there!

Thank you for reaching out to us. Our 15-180 pivot shoe appears to match what you have here. This is designed to work with the Series 190 coil springs and 15-181 double support clip. Look over the specifications and see what you think.

We can help determine the proper coil weights but we will need you to weigh the window sash on a scale and get back to us with the precise weight. 

As for the pivot bar, may we see an undamaged version removed from the sash? 

Correct. You would want to divide the sash weight by the total number of springs in the window. 

I'm not sure I understand. These parts are non-handed so they can work on either side of the window. 

We don't recommend converting to the Series 140. As a policy, we always recommend sticking with the original hardware that your window was designed to use. 

With a 21-pound sash, you can use (2) S190-540 5-pound springs on both sides of the window which will total 20 pounds of overall support. This setup should work for you so long as the coil weights are within a pound of your sash's weight. We don't sell this exact pivot bar but our 26-378 is similar. Take a look at the dimensions and see how they compare with yours.

The Series 140 is compatible with a handful of pivot bars. You can start by taking a look at the 26-398, 26-405, and 26-454 but you will have to review the specifications for each to see if at least one of the hole placements aligns with your old pivot bar.
