Good evening.
I need to replace a 29" Non Tilt Block and Tackle Window Balance according to the attached pictures.
It seems the accessories dimensions (according to my own measurements) match the attached image.
Let me know if you can help.
Kind regards,
Renato
Thank you for writing in, Renato. Based on your measurements and photos, our S385-29 may work in place of your current balance. Look it over and let us know what you think. Since your stamping does not match with any of our stampings, you will need to weigh your sash on a scale and refer to the sash weight chart on the product page to decide on the most appropriate option for your balance.
Very well, Renato! Let us know how you make out, and many thanks for considering our business. We appreciate it.
Renato, the company that made your balance tried to compete with other balance manufacturers by using less metal in making the balance channel to cut down on size and the cost. Eventually they went out of business. All balance manufacturers use the same standard size balance channel for your side load window. The important parts are the nylon ends, especially the bottom shoe. Measure the depth of the old shoe and see if it matches the shoe on the new balance. On the lengths, the old and new balance should be 29" with a spring weight (2820). I pulled up another media guide title "How to replace a window sash balance" to further help you.
How about taking a look at our S380 channel balance. measure the depth of your bottom balance shoe as it shown in the diagram below and see if this would make a better option for you.
