I am sorry, I do not understand your inquiry. Do you need help choosing the proper spiral balance? Is "l7l2k4" your stamp?

Paul from SWISCO responded:
Yes, the Series 400 Spiral Balance can be used with wood windows. Please take a look at the 17-026 Bracket, #S 32.

Dave from SWISCO responded:
The Series 400 are normally used for light weight windows, generally up to 22 Lbs.. The fittings that go with Series 400 are #17-030 or #17-031.
If the sash is heavier, like 30 Lbs., then look at Series 500 with #17-007 or #17-012.

How do you determine the correct length of a spiral balance for non-tilt window.(window sash is 27 3/4" L)

Paul from SWISCO responded:
We recommend you remove the balance and measure the metal portion of the balance only. This will determine the balance length.
A handy person from burlington ontario canada says:
Paul,
do not have the existing spiral balance to measure the length, (sash 27 3/4")

In order for us to help you identify a replacement, we will need the length of the metal portion of the balance.

Sorry, do not have the exterior metal portion of the spiral balance. Do have the interior metal spiral part which measures 27 3/4". Does this mean I should order a 28" spiral balance?

Paul from SWISCO responded:
The channel portion will be shorter than the inside portion (spiral). I believe the S400-27 Spiral Balance and S500-27 Spiral Balance are both viable options. As stated earlier, the Series 400 are used for light weight windows, generally up to 22 lbs. The Series 500 would be used for windows weighing upward to 30 lbs.
