Sampedro's Clock Boutique presents for sale a set of 5 suspension springs of different sizes for American Clock. Its measurements are: 3-3/16”, 3-3/4”, 4” , 4-1/2” , 5 3/16”. Those are the measurements commonly used in these American Clocks. You will also find them separately here in my eBay store but this is a cheaper option because it offers more at a lower cost. In addition, this set will allow you without fail to obtain the suspension length for your clock and have spare parts that you can use in future projects. If you would like a different size just let me know and I will make it for you at a fair and reasonable price. If you have any questions feel free to contact me. I also invite you to take a look in my eBay store where you will find more than 400 items, at incredible prices, that will be useful in your restoration work. Every week we renew our inventory so I suggest you like me among your favorites and so you can receive alerts for new items. Thank you !!
