I think I've identified my replacement channel balance for my aluminium mid 80's Milgard windows at the S385. The ones I a replacing have 2640 stamped as my sash weight code which is not an option with the S385. Which weight should I order?
Thanks Nick

2640 is the weight code you need to order. This is an option for Series 385. You can find it on the S385-27 webpage.
