Replacement parts needed

Thanks for posting, Carrie! Please see the list of hardware I made for you on this page. They're a little different from what you have now, but I think they will still work.

As for the springs, I recommend our Series 150. You mentioned you couldn't find any numbers on the old parts, does that include the springs? You usually want to pick the best Series 150 option by the stamp on the old spring. If you can't find anything, please give me the exact weight of your sash and how many springs are used on each side to support it and we will calculate the proper option.

It sure does. With a nice even 20 pound sash and two springs on each side, I recommend our S150-5. Each of these carry 5 pounds each, so having 4 altogether should be perfect for your sash.

Yep, looks good to me! Just one note about the 15-143 bushing, 15-144 cap, and 15-145 barrel. These kind of "sandwich" over the spring. You put the 15-145 barrel over the round post on the 15-144, put the spring over that, then snap the 15-143 on.

I only explain because many customers have voiced confusion on how these relate to one another. Hope it makes sense. Let me know if you have any questions.

My pleasure. Thanks for considering us, and please let me know if we can be of any help in the future.
