In you help section I have come a cross a past customer who has the exact balances I have (see photos) and link below. I am guessing that the "37" marking may be for the window sash and glass weight. I have weighed my window sash and glass and it is ~38lbs.
Please see photos and link below and let me know what I need to do to get (2) balances on order.

Okay, we finally have all the info we need. I'll email you an order link and price quote for 2 balances with a 3460 option, which should be perfect for your sash weight. Let me know if you have any questions. |
