Coil Balanace Part Finder Request

Hi Swisco Team - I have a coil balance, single sash window. The coil is disconnected/broken on one side and the shoe is broken on the other. I *think* I've narrowed down the spring to a Series 160, 6.5lbs, and a 17/32" 15-199 shoe. I'm lost on the top plastic block part.

Hi there!

Thank you for reaching out to us. I agree, the pivot shoe you have matches the 15-199. It looks like you have a double-spring setup, so I recommend the 15-150D support.

Please let us know if you have any questions.

Thank you!
Are any other parts needed, other than 2 springs (per side, 4 total), 2x 15-199 shoe, and 2x 15-150D support? I'll hold on to the screws in the current supports to be replaced.

You only need to replace what's broken, so you won't need any additional parts if the rest of the related hardware is in good shape. Just note that the springs are sold separately.
