What Kind of Channel Balance and clips should buy to replace the broken one?

Question

Hi Customer Department,

I want to order two channel balance and the clips to replace old one. First, the old style is 30 4 FN CALDWELL (please see attached pictures). I bought 31" 3030 to replace but they broken again. Could you please help me to identify what's kind of the channel balance and clips can replace the old one? Second, I bought another three channel balance which is S-385-34 from you on 7/2/2018. I wonder what kind of the clips I should to buy?

Thank you for your help in advance!

Thanks for contacting us. One of the reasons the balance you bought broke could be because the stamp was wrong. For a 30-4 stamp, you should have gone with a 3040 option. 3030 would be too weak.

I'm also not sure what Series you chose. The stamp isn't an identification code, it only tells you how the spring is calibrated. Series is determined by referencing the nylon attachments on either end of the metal channel. Yours looks like it could be our Series 395.

I would refer to our Series 395 with a 3040 option. You may want to weigh your sash on a scale just to confirm that the 3040 option will work best.

You also mention clips in your post, but I don't know what that means. The word "clip" could apply to a half dozen related parts. Could you specify? Seeing a picture of it would be a huge help, too.
