Channel Balances

Question

I'm looking for two different lengths of the same channel balnances for our non-tilt Milgard windows. The long ones measure 19 inches, I need four of those, the shorter ones are 15 inches and I need two of those. The stamp on the 19 inch one is "18 5 GT CMC 2" and on the 15 inch on is "14 5 GU CMC 5." Please let me know if you need additional information.
Thanks

Thanks for posting! You have either the Series 380 or the Series 385 Channel Balance. To confirm the correct series, you'll need to measure the depth of the bottom shoe.

You'll need the 1450 (support 13 to 17lbs) and 1850 (supports 17 to 20lbs) stamps.

Comparison of the S378, S380 and S385 balance shoes.
