Good morning! Thank you for contacting us. No, I don't believe that's the S800-29 like you just ordered. We have put it on hold for you.
I agree in that it looks like either our Series 351 or Series 390 channel balances, but I can't tell which one based on these images. Which is closer? The key factor is the bottom shoe, so look at our 15-001 and 15-002 and see which dimensions better match your own bottom shoe. |

Usually balances like this have a stamp one digit below the length, so 28 3 makes sense in this case. For another example, a 23" balance would have a stamp like 22 4, or maybe a 15" balance would have a stamp of 14 5. See what I mean?
Is 20 pounds the exact weight? The reason I ask is, two S390-28 balances with the 2730 option can carry a window sash weight of 13 through 19 pounds. Double check just to make sure. If it is 20 pounds, or even more, then it would be best to go with the 2740 option. You can see the list of options and what weight they can support on the S390-28's page. |

No, a stamp of 28 3 indicates a 29" long metal channel. Usually, stamps have two numbers. The first one is often one digit less than the length. A 29" balance would have 28 3, like yours. A 23" balance would have 22 4, and a 15" balance would have 14 5, just to name two random examples. This isn't always the case, but for this type of balance that's the rule of thumb.
To change your order, you can simply request that your current one be cancelled, and then place a new order. |
