I am attempting to identify and purchase replacement coils. The white plastic housing for the coil shows 6 R
I do not know if that means anything. Please assist me in identifying the correct coil for my window.

Thank you in advance.

Thanks for posting. I believe you have an older version of our Series 140 Coil Balance system. A '6' stamp for this particular balance system means you need the S140-6 6 pound system. Let me know if you have further questions.
