15-004 vs 15-005?

Handy Person from California
I think I need a Series 385 33" length. I am not sure about the shoe whether it is a 15-004 or an 15-005 or other. I am not able to see a discernible difference to be sure I am getting the correct part. How can I tell them correctly to order? There is no number on the old balance.

Thanks for posting! The difference is actually in the depths of the two shoes. Please take a look at our 15-004 and 15-005, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Thank you. In that case, I think that our S385-33 is a good choice. Are you sure that there is no number on your original balance? If not, can you please give us the weight of your window sash? You can find this out by removing the sash from the window and placing it on a scale.

Looks like the 004 as it is just under 1 1/8 "

Yes there is a 32 4 JP Caldwell on one. Which option should I select, 3240?

Thanks

Thanks for getting back to us, Andy. Yes, a 32 4 stamp would correlate to a 3240 option. The 3240 option can carry a window sash weight of 23 through, and including, 28 pounds. Does that sound about right to you?

Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
