Hi Bob. This is an old block & tackle rod balance that can be replaced by our sturdier Series 775 Channel Balances. You will need to measure the length of the rod to know what length to select. You will then need to measure the weight of the window sash as well as the size of the bottom shoe to know what option you need. If you need to replace your pivot bars as well, look at our 26-021 or 26-241. Compare the dimensions listed in the pictures on each product page and see if either could be a match. |

Hey, Bob! What you're showing us here is the pivot bar, not the shoe. The shoe is what this pivot bar inserts into. It should be nylon part at the end of the balance cord. |

Yep, that's what led me to suggest the Series 775. You just need to measure the width of that shoe. If you have an S775-30 balance and your sash is 15 pounds, then you either have the 30B & 1" shoe option or the 30B & 1-1/4" shoe option. |

Great. If you have any other questions, let us know! |
Hi Bob.
Installation of the first window went ok with two exceptions. First they sent me two left hand latches. Not a big deal since I will be ordering more parts for the remainder of my project. The second was I could not figure how to get the shoe into the slide without cutting a notch see picture. Is there a trick that I need to know or is this typical? As you can see mission accomplished as the widow stays put now:)
Thanks for the help Bob.
Bob

Cutting a notch is usually a good way to get a pivot shoe out, assuming there isn't enough room to pop it out through the track. We do it all the time. However, we highly recommend cutting the notch at the top of the track for the bottom sash. If the notch is at the bottom of the track, then the shoe could slip out when you raise and lower the window. This could be a problem. You will want to find a way to patch that cutout. As for the 7.5 pound sash, we don't have anything to support that kind of weight now but we will look into it for you. Can you just confirm that the shoe for that window is also 1" wide? |

Thanks, Bob! After looking into it, it appears that the 30A stamp will work well for your sash weight. However, it's very rare, which means we can only provide this as a custom order. I will email you an order link and price quote right now for 2 of these with that stamp. My colleague Paul also looked over your photos and he believes you can take the shoes out without making a cutout. He told me that you just need to twist it out to slip it out of the track. |
