24C B.S.I. LM what does that mean? Hi George. This looks like it might be a Series 775-24. Look it over and see if you agree. You'll need to measure the bottom attachment of an undamaged version of this balance to see what size shoe you need (1" or 1-1/4"). The stamp code of 24C refers to weight range the balance is calibrated to support; in this case, a window sash in the weight range of 17 through 22 lbs. Finally, does your old balance screw in at the top to the window track? I assume it does, but check this to be sure. Many thanks. |
