Need Replacement Retainers

A quick learner from Florida says:
Hello,

I have windows that are approx. 9 years old bearing the labels: Series:Mark 40/50 Premium STD - AAMA/NWWDA 101/ I.S. 2-97 - H-LC25/35-52X96. The retainers that keep the spring loaded balance are breaking at the top and allowing the balance to move out of the window. Need replacement caps (not sure which ones) and any instructions available.

Thanks, Jason

The part you are looking for is referred to as a top sash guide. Unfortunately, I am not able to identify it based on these pictures. I will need you to remove it and take a few pictures of it by itself.

It's easy enough to take top sash guides off. Just remove the sash and unscrew it. To see how to remove this kind of sash, watch the video below.

Perfect, thank you! See our 18-166 and let me know if this is a possible match.

That looks like them!Thank You

I also need a channel balance as the strings inside are breaking, but cannot locate the ones I have on your site. The window information is H-LC25/35-25X96.

Thanks for the help,
Jason

Sure, no problem! As for the balances, I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385.

Now, as you can see, the only difference between these two Series is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.
15-004 and 15-005

Looks like the 380 series is the one I need with the 15-005. I am assuming the numbers on mine "29-6" is stamp option for "2960 32 to 35 lb" correct?

Thanks,
Jason

Yes! A stamp of 29-6 does typically correspond to our 2960 option. It may be a good idea to weigh your sash just in case.
