SWISCO - The Replacement Hardware Authority

stamp number

A handy person from fort myers, florida says:
I need a S385-36 balance, the one I took out was stamped 3518. Which option would I pick for that stamping. I was not able to weigh the window, it is 32x36 double pain aluminum frame.
Thanks for your help.

That's an odd stamp. What is the weight of your window sash? You can remove it and place it on a scale to find out. Then, compare that weight to the chart we have for the S385-36 to determine the best option. If your weight does not fall under any of the options listed on that chart, let me know.
