Cover for coil balance

Thanks for reaching out to us. We don't sell that exact white plastic cover, unfortunately. We do sell the shoe and spring, though; those would be our 15-175 and Series 152, respectively. We do sell covers for the Series 152 but they're a newer style and I would wager they are the same as what you got with your new hardware: the 15-143 and 15-144, along with the 15-145. These parts all kind of "sandwich" over the spring.

I'm not sure why your window is bumping into the new cover, though. It's not like your old cover is particularly shallow in the track. Can you go into more detail about that? What part of your window, exactly, is hitting it? Can you also show me the new style cover, assuming the parts I mentioned don't match?

I think I know what you mean. There are some coil balance assemblies that are designed so that the top coil has a longer "tongue," allowing it to reach down further without much effort.

Unfortunately, these coils are not designed like that. You just have to do it the old fashioned way, which is screwing the spring to the shoe and stretching it up. Trust me when I say that this can make it a little awkward, since they're still under tension and liable to get away from you, but it can't be helped. That's just how these are made to work.
