I need 4 balance rods for norandex windows in palm beach Florida. The metal part is 1/2 inch wide and 37 inches long. The number stamped on it is 3635. I'm not sure if it's a series 380, 385, or 390. If you could let me know I would appreciate it. Thank you. Robert
I need 4 balance rods




Hello Robert!
Based on your photos, it looks like you might have the S378-37. This comes attached with a 7/8" deep shoe so we recommend you measure yours to confirm. To determine the correct stamp option, we will need you to weigh the window sash on a scale and tell us the precise weight.
As for the top sash guide, take a look at the specifications for the 18-161 and see if they match what you need.




hello this is Robert again I measured the items and it is the s378 & the 18-161 I also weighed the sash & it weighed 23lbs I would need an estimate on 4 of the balance rods & 4 of the top sash guide & 1 of the top window beauty 3 sided rectanguler trim piece that fits in the window frame. The metal part of the balance rod is 37 inches long & the stamped number is3635. thank you.



Thank you for getting back to us. Since the sash weighs 23 pounds, you can use the 3630 or 3640 stamp option. A pair of balances with the 3630 stamp option can support a sash weighing 18 to 23 pounds, and a pair of balances with the 3640 stamp option can support a sash weighing 23 to 30 pounds. The decision is ultimately yours. Pricing for our parts can be found on each of the product pages and all orders can be placed on our website.
The trim piece doesn't sound like something we have but we would need to see photos of the part as well as the end profile to confirm.
