Based on your picture, I think our Series 795 channel balance looks like our best match. This comes with a 1-1/4" bottom "T" shoe and screws in at the top, which appears to match your configuration. See what you think.

To remove the bottom T-Lock shoe, you would press in the nylon pins that lock into the channel balance holes, swinging the shoe away from the channel rivet and out. After you remove the shoe, see if it looks like one of ours. I hope this helps!

The spring weight usually is stamped on the metal portion of the actual balance. If it's not, you would need to remove your sash and weigh it on a scale. There is a chart on the product page that will tell you which option to go with based on the sash weight.

You have a MI vinyl window that uses the 15-180 pivot shoe with the Series 190 coil springs. The coil spring will have a number stamped on it for the spring weight. The other parts are the 15-186 coil spring detent and 15-182 coil spring bushing. |

The plastic that covers the spring has to be removed at the same time as the spring. Ideally the entire coil balance assembly comes out as one unit. I would definitely watch the video as a priority, that will show you how we do it step by step. A 30 pound window is fairly heavy for coil springs, but not unheard of. Assuming that you have two springs per side, you can use one 7 pound and one 8 pound spring for each assembly. Adding those together, that gives you 30 pounds of total support. |
