Kinko non-tilt window balance

A quick learner from florida says:
I have a few Kinko windows that seemed to break all at once . I looked through your examples & non look like the top of the balances I have . Can others be substituted ?

Balances are 30" long & the only thing I can make out on the balance is IW CMC 7 , 1/2 " balance ,Any help would be great.

Hey, Mike. Looks like your top is similar to our 19-005. I think that should be fine, yours is just a slightly different style. It should still serve the same function.

How about our Series 385 channel balance? Does that look good? I'm not sure about the option, though. Is the stamp on the other balance easier to read? If not, you'll have to remove your sash from the window to weigh it. Then, compare that weight to the weight ratings we show for each balance and see what matches up.
A quick learner says:
Windows weigh in at 33# & those you spoke of I think will work.

Thanks ,Mike

Great! If these window sashes weigh 33 pounds, then I recommend our 2960 option. Two S385-30 balances with this option can carry a window sash weight of 32 through 35 pounds.
