Plain channel with a knife lock shoe

Hi there, Randy.

Thanks for contacting us. At first glance, this looks like it could be our Series 751 balance. However, it looks like your metal channel may be squared off instead of ribbed. Can you show us a photo of the metal channel, straight on, to confirm? You can use the photos on the page here as a reference for what I mean. 

The 26TG stamp doesn't match up with any of our options though. We'll need you to weigh the window sash on a scale and get back to us with the precise weight, I'm afraid. 

Thank you kindly for getting back to me, Randy. This will indeed need to be a custom order based on the photos and information you've given us. What we'll do is take the S770-27 plain channel balance with the 27D stamp and swap out the terminal clip for the 15-014 knife lock shoe. A pair of balances with the 27D stamp will support a sash weighing 22 to 26 pounds. Just note that our balance does not come with the metal bracket shown in your first photo. 

Does this sound good to you? If so, I've just emailed you a purchase link and price quote for (2) balances that you can use to place an order on our website. Please let me know if you have any questions! 

It was my pleasure, Randy. Please let me know if you need anything else!
