Window part needed

Thanks for posting. This is called a coil balance system. It regulates the movement of the window sash. I am sure we can help, but I am afraid you will indeed need to remove the assembly from the window for us to properly identify it. With rare exception, these coil balance components are used by many different manufacturers, so the only way to confidently identify something is from clear visuals and dimensions. 

Specifically, we'll need you to remove the entire assembly, including the 'pivot shoe' further down the window track that the coil springs attach to and from which the window pivots. The identity of the pivot shoe determines the coil springs you need. We will also need the thickness of the coil springs; it should be either 3/8" or 5/8". Finally, we'll need any stamps on the springs themselves. These are typically found near the 'tongue' of the springs. If there are no stamps, just give us the exact weight of the window sash the coil balances support. A bathroom scale should suffice for this. 

The video below shows how to remove and replace a similar coil balance assembly. Let me know if you have any questions. Once you get us the information explained, we'll do our best to find what you need.

That's a huge help, thanks! We do supply the parts for this coil balance assembly, though they're sold separately. I'll list them for your convenience.

• 15-111 pivot shoe
• Series 160 1/2" thick coil spring
• 15-150D double spring support

I feel confident these parts will work for you, but make sure to measure your spring to ensure that it's the same thickness at 1/2". There is another size option that's a little smaller, so if that's what you have then we should be able to accommodate. Note that you will also need the stamp printed on the old spring so that you can select the appropriate weight option.

Please let me know if you had any other questions!

Sure, that would be our S160-05. These carry 5.5 pounds each, which should match yours precisely. That means having two 5.5 pound springs on each side gives you a total weight support of 22 pounds. You can always weigh your sash to confirm that that's right.

One last note: I note that your old stamp says 64", which likely references the travel length; or, in other words, how far it stretches. They don't make springs that long anymore, and our S160-05 only stretches to around 35" to 40". With that in mind you will likely need to install these lower in the frame to make up the difference. Just make sure not to install them where they would interfere with the tilt latch.

You're very welcome! Please feel free to reach out if we can be of any further assistance.

Hey Mike. These parts are known as tilt latches. Yours in particular appear to match our 26-243 and 26-244. I suggest comparing our dimensions to yours before you buy anything, though, just to be sure. We do also have an installation video on these.
