Trying to replace a balance for a Milgard window that weighs around 32lbs. The current balancer (pic) shows 26 9 AX CMC 1, with the metal rod measuring at 27". Currently looking at this: https://www.swisco.com/27-inch/pd/Series-385-Channel-Balances/S385-27 (would it work?).
Not so sure about the sash weight as the window only weighs 32lbs but the 26 9 (which I'm assuming corresponds to 2690) suggests the current balancer can hold a lot more sash weight. Can I get by with just ordering the 2660 version? I'd like to keep the other balance that does work so will just replacing the broken one (on the left side of the window). Thanks!

Most Milgard windows like yours will use S385-27 side load balances. The code "26 9" is for a sash weighing between 33 and 34 pounds, so you can use "2660," for a sash weighing between 30 and 33 pounds. However, you don't want to swap out just one balance. The tension won't be even between the balances, which puts undue strain on the new balance. It's like a pair of shoes. You need both sides to be broken-in the same amount. |
