Thanks for posting. I recommend that you weigh your window sash and compare it to the options available for the S751-17:
16HD: Two balances with this option can carry a window sash weight of 17 through 22 pounds. 16R: This option can carry 10 through 17 pounds. 16TG: Finally, this option can carry 22 through 24 pounds. |
