Look for a stamp code on the metal channel. If there is none, or you are uncertain, obtain the exact weight of the window sash. You can then match that exact weight with one of the weight ranges listed alongside each and every stamp option on a given balance's product page. |

I'm afraid it does. You want the stamp option you choose for your balance to properly reflect the weight range that your sash's exact weight falls into. Anything else will not work properly with your window. If you can give us that exact weight through some means, we can help. Otherwise, I am afraid there's not much we can do. |

No worries Pete, I saw to it that your order was cancelled. To obtain the exact sash weight, remove the window sash as shown in the video below, then gently place it on a bathroom scale. That should give you a precise enough reading. |

Hey Pete. These appear to be either Series 380 or Series 385 Channel Balances. The difference between these two balance Series is the 'depth' of the bottom nylon shoe, or what can be thought of as the 'heel-to-toe' measurement. See the image below for details. Comparison of the S380 and S385 balance shoes.
Have the customer measure the metal channels, but not including the nylon fittings at either end, for the length. Most likely the balance you state is 25" is really 24" in length, which means it would either be an S380-24 or S385-24, with a stamp option of 2330. For the other balance lacking any stamp option, first off, measure it correctly to see if it's in fact a 29" balance. Secondly, it's not the weight of the balance itself that matters, but rather the exact weight of the window sash that the balance supports. You can match that exact weight with one of the weight ranges listed alongside each stamp option under the product description on each and every balance's product page. I'm not as certain of the Top Sash Guide. Can you show me a clearer picture of its front? |

This looks like our 18-147 Top Sash Guide possible, just review the dimensions to confirm it matches up. Now, unfortunately some of our balances have indeed been out-of-stock, as our suppliers have been working with limited staffs during the public health crisis. However they've been gradually returning to stock, so if you sign up to be auto-notified we'll let you know the moment they again become available. |
