Sash Weight

Hello,

We can supply your balances with the 19-005 top and 7/8" deep 15-029 bottom fittings but it will need to be a custom order. Before we get started, I would recommend double-checking your length since balances stamped with 2690 should have a 27" long metal channel, not including the end fittings. 

The 2690 stamp is also from an outdated weight system, so we will need to know the exact weight of your window sash to confirm the corresponding strength option for your replacements. Lastly, we'll need to know the number of balances that you need with the minimum being two. Thank you! 

Thanks for getting back to us. Unfortunately, knowing the size of the window does not tell us the weight of the sash. The 30 in the stamp code may or may not be related to the sash weight. Balance manufacturers often include additional numbers and letters after the strength code for various purposes. The only way to confirm the correct strength for your replacement balances would be to weigh the sash itself. 

The sash refers to the part of the window that you raise and lower, including the frame and glass. 

As for using 2650 strength options, we'd be happy to supply an order link and price quote for those balances with the 15-029 shoe attached but keep in mind that custom balances can not be returned for a refund if the sash weight differs, which is why we strongly recommend confirming the exact sash weight before ordering. Just let us know how you'd like to proceed.
