Gorell double hung tilt

Question

The sashes seem to weigh (I only have bathroom scale) about 27 lbs each. I have about 35 of these Gorell sashes with coil balance problem. I?d rather rebuild than replace them.

Please let me know what you think. Do you have an installation viideo to help me get the first install done right?

Thanks, Bob Eremian

It looks like you have our Coil Housing Pivot; 15-087 and Tandem Coil Housing; 15-086. These are typically used with the Series 180 Coil Balance. Check for a number printed on each coil that indicates the number of pounds it can carry. If you are unable to find the numbers, you'll need to go by your sash weight. Divide that weight by four and each coil will need to carry that weight. For example; if your sash weighs 28 lbs. you'll need four 7 lb. coils to support it. I have associated a couple of installation videos that may be helpful.
