Replacement channel balances for Jordan windows

A home owner from Henderson, NV says:
I would like to order four replacement channel balances for two Jordan window sashes and request your help specing the correct part(s). I believe I need four S390-29's but I'd like confirmation. Also not sure of the option I need.

The dimensions of my balances are 29" length X 9/16" width X 5/8" depth. The information stamped on the back of one balance is 28 4 K 1 and the other is 28 4 G 1. I'm positive on the 28 not quite as sure on the K 1 and G 1 as they a pretty scratched up. The window sash weighs about 34 pounds. I believe the weight has something to do with a four digit option number related to the specific balance I need.

Please confirm the part number and option I need and I'll place my order.

On a second matter unrelated to the above. I have a Jordan window with a cracked external pane on a dual-pane thermal window on the stationary window panel located above the sash. Can a glassier replace that panel or must I buy an entire new window?

Thanks in advance for your help.

Hi Gary,
A 29" Series 390 with a stamp beginning with 28 4 will normally translate to 2840. To check remove the window sash and place it on a scale to get the weight in pounds. You had told us 34 pounds and a special weighted balance may be needed if it does measure 34 pounds.

A 29" Series 390 with stamp 2840 will carry a window sash weight range of 23 through and including 28 pounds.

This 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.

If you would like us to check the balance series you selected, please post a few photos for us to research.

For the cracked external pane you will need to replace with new double pane insulated glass. Normally you can bring in the sash to your local glass shop. They may need to take the sash apart to get the proper measurement to have the glass manufactured for you.

Thanks Donna-

My balance looks exactly like the one pictured in the post from Tommy in Niceville, FL. Mine is also a 29" balance stamped with a number 28. My window is a large double pane with a sturdy aluminum frame measuring approx. 46" x 30" and I confirmed its weight at 33-34 pounds. Will a 2850 carry that weight or should request a quote on your website for a set of special balances for this application?

Thanks.

Hi Gary,
29" Series 390 Balances with 2850 stamp option will carry a window sash weight range of 28 through and including 32 pounds

For a 33 to 34 pound sash we suggest the 2860 stamp.
2860 stamp will carry a window sash weight range of 32 through and including 35 pounds.

This 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.
