Hello Chris. Please see our 15-192 pivot shoe, 15-156 spring cover, and #15-157 balance drum. For the coil spring, check out our Series 170 balance. You will need the number on your existing spring when ordering to determine the best option.

Hmm... that's kind of an odd one. How about this: tell me how many springs are used on each side of the window, and the weight of the sash. With that information, I will be able to determine which option is best.

Thank you. If your sash weighs 20.8 pounds, you may want to consider using four S170-335 springs. Each of these can carry 5 pounds each, so four working together (two on each side) should work well for your sash.

There should be plenty of room in the jamb for two. To insert it into the slot, just put it in the cut-out shoe first and slide the whole balance system in.
