Balancer for Milgard window, series 5220/5270, H-C40-54x90

Thanks for posting. See the S380-33 or S385-33 Channel Balance. The difference is the shoe depth; see below. For a stamp option choose 3250.

Comparison of the S378, S380 and S385 balance shoes.

Sounds good to me. Let us know if you have further questions!
