Is my balance Series 351?

A quick learner from Pearland, TX says:
Series 351 looks like the good start. The top of my balance is however winged as in 19-005, Channel Balance Top, Winged. The dimensions of 19-005 are the same as in my balance top. The shape of the shoe in series 351 is the same as mine, however the width of my shoe is approx 1 1/16" which is between the width of 15-001 and 15-002. Please see attched pictures.

Thanks for posting!

It appears that you have a top attachment of 19-005, and a bottom shoe of 15-001. This is our S395 channel balance series.

Before we get started, though, I will require a bit more information. Can you please tell us what any stamps or markings on your metal channel read? Can you also remove your sash from the window and let us know the weight in pounds? This will help us determine the appropriate option for your balance.

The markings on the metal channel read
2740 HJ B.S.I.
I was not able to remove the sash from the windows, but I estimate its weight to be between 20 and 30 pounds.

Thank you for the information! That should be about everything. You will need to order S395-28 with the option 2740.
