Need help identifying top and bottom attachment

Question

I need to replace 2 of these for my windows. The stamp says it's a 2740 with an RB stamp after it. Any idea what the RB means? Also, can u please tell me what my top and bottom plastic attachments are and which 2740 channel balance you would recommend that comes with them? Appreciate your help!

Thanks

Jason

Hello Jason,

Take a look at our S395-28 with a 2740 spring strength option. "RB" is just manufacture information but based on your balance attachments and stamp number, this should be the balance you need. Thanks for posting!
