My Aliside Ultramaxx vinyl window (#053-462941, 27 5/8 X 44 3/4) has a broken shoe/ balance coil. The bottom sash in question weighs 14 lbs. Do I need a 15-177? You answered a previous person and my issue with same window seems the same. But, maybe not. Help please, photo attached

Thanks for reaching out to us! This indeed looks like the 15-177. If the specifications match up then you're good to go! For a 14-pound window sash, I recommend using one S152-7 7-pound spring on each side of the window. Take a look and let me know if you have any questions.

How do I attach the coil to the shoe or does it come together? Order separately?

The coil springs are sold separately from the pivot shoe. The spring is then attached to the side of the 15-177 using a screw like the 33-072.
