Hello! Please see our 15-111 pivot shoe, which is designed to be used with the 1/2" thick Series 160 coil spring. These parts may be what you're looking for. If you can't reuse your old cover, you can use our more modern 15-150S. Please review these products and let me know if you have any questions. |

Hello! I'll answer your questions one at a time. 1A: Yes! The 15-191 should be perfectly fine. They're more or less the same part, the 15-191 is just made of a somewhat more durable material. 1B: These balances are perfectly interchangeable between the left and right side. 2: Now that you mention it, I actually can't tell if your old cover is single or double. I thought it was single, but if you have two springs per side then I'm way off. You want the 15-150D. As for how the springs connect, they kind of stack on top of each other like that old Monkeys in a Barrel Game. The bottom coil hooks into the pivot shoe, then the second spring hooks into that first spring. You can see a little hole in the Series 160 that will take the hook. 3: There should be a stamp printed on the old coil spring that tells you what option to pick. If the ink is too faded, though (which happens a lot), then you'll have to get the exact weight of your sash. I can use that to calculate which weight option to go with. 4: Travel distance actually isn't that important these days. Once upon a time, there was a great variance between coil balance lengths from window to window and manufacturer to manufacturer, but modern coil springs are all pretty much the same size. It still may be a good idea to measure just to be sure you don't have to remount your balances, which is sometimes necessary when the old coils were reeeeally long, but I find that to be pretty uncommon. I guess it can't hurt to be sure! Hopefully that clarifies things. Please let me know if you had any other questions. |

Thanks for getting back to us! So, it's a good thing you measured your coils after all, because you have the older style. They don't really make coils that long anymore; most standard coils are 35" to 40". That means you will have to mount these lower in the sash. When you do this, make sure to put them under the tilt latch (specifically, the position they're at while the window is closed). Otherwise the latch will bump into them when you open and close the window. This will require drilling new installation holes. If you have two 5.5 pound springs on each side of your window, then that means your sash is 22 pounds. If you want to convert your window to only use one coil per side then you'd need an 11 pound spring, but we unfortunately don't sell that size. I'm not sure they even make that. 10 pounds is the heaviest we sell, under the S160-10. That might work but honestly I think you should just stick with the S160-5. If it ain't broke, and all that. It's ultimately up to you. |

Sure. So, our shorter springs will still work fine, but if you install them where they went before (at the top of the window), they wont have enough travel to close your window. You'd be fine mounting them around halfway down, but the issue is that the tilt latches on the top corners of your sash will bump into them, preventing you from actually opening the window. To get around that, just close your window and take note of where the tilt latches are. Then you'd simply install the new coil assembly under that. Your window will still open perfectly fine but that way the tilt latches won't get in the way. |

Awesome, glad to hear it! Thank you so much for your business and please let me know if we can be of any help in the future. |

That's great news! I'm so glad to hear everything is working out, shy of one cover. That crack sounds like it was our fault so I'll make sure we send you out a new one ASAP, free of charge. Hopefully that makes up for it. As for the tilt latches, I recommend the 26-243 and 26-244. I feel very confident these are just what you want. |
