type of coil balance to buy

Question

Hi, I am attaching pictures of window sashes assembly, notice the metal pin on each corner of the window sashes has a round metal head, which requires wider opening on the pivot shoe metal brake slide-in notch? The window sash weigh 8.4 lb. Please let me know what type of coil balances I should buy, is it S140-5? Also, how much do you charge for shipping to California?

Thanks dehua

Hello,

I would recommend removing your coil assembly to compare to the 15-177 pivot shoe, which uses the Series 152 coil springs. Based on your sash weight, I would recommend using one S152-4 coil on each side of the sash. Take a look and see how the specifications compare to yours.

You will also be given multiple shipping options to choose from once the parts are added to your cart and you input your postal code. Thanks for posting!
