334 spring stamp

A handy person from Saugerties says:
My upper windows slam down when unlocked. Not sure what I need to repair them. See attached pics. Plastic says certainteed and metal "tension" ring says 334. I need to repair 4 windows, can you forward part numbers needed?

Hello there!

This looks like an old Simonton coil balance assembly that isn't made anymore, but take a look at our 15-259 pivot shoe and Series 159 coil balances. The video below will walk you through the installation process. 

A handy person from Saugerties says:
What is the lb of the coil balance I need. The original is marked 334

Thanks

The "334" stamp doesn't match any of our standard coil weight options. With that said, we suggest weighing your sash on a scale to determine the appropriate coil spring weight. Get back to us with the exact sash weight and we can work it out from there.

Thank you, will weigh sash and get back to you

We'll be here!

A handy person from Saugerties says:
My sash weighs 9lbs. I have 5 windows I need to fix. Can you advise how many coils I need and how many pivot shoes and advise if any other parts are required?

Many thanks!

Thank you! If your sash weighs exactly 9 pounds and if you have a total of (2) coils in the window (one on each side), you'll need (2) of the S159-4 4.5 pound coil balances. One of these on each side of the window will support a sash weight of 9 pounds. The video I linked you to previously will go over the parts you'll need and how to install them.

If you have any questions just let us know!
