Coil Support Springs in a 'Cardinal' brand window, mfgr.Bridgeton MO (circa 1992)

I'm afraid that those stickers don't tell us anything about your windows or what balances they use. Can you show us a photo of the balance itself? That would be a big help. In the meantime, see our video below. This may offer some insight on how this hardware works.

Thank you! Okay, we're getting there. These pictures are a big help. I can narrow your spring down to either our Series 160 (1/2" thick) or Series 165 (3/8" thick). Measure the thickness of your spring to determine the better match. The only question after that is to determine which option would be best. I'll go over that a little later in this post, since it's a little complicated; let's address your other questions first.

Looks like your window used 4 springs on each side. This means that your cover is very tall. I can understand now why you were having trouble removing this. Unfortunately, there's no real trick to getting this out of your window. You want to remove this through the same cutout that you used to remove your springs. If the cutout isn't big enough for your tall cover, you may need to cut it a little and make it tall enough. Review the video below for more info on how this can be done.

Oh, I almost forgot about your tilt latch. I can't tell exactly what you have from that photo but it's very similar to our 26-243 and 26-244. Remove an undamaged version of your latch from the window and carefully compare it to the dimensions and pictures we show. I think there's a good chance they'll match up.

Okay for your top tilt latches, use 26-243 and 26-244. See our video on removal and installation. For the triple coil springs, the pivot shoe will be 15-191,the triple cover will be 15-205 and for the 3/8" coil springs for a 20 lbs. sash, use two S165-3 and one S165-4 on each side of the window.

Thanks for getting back to us with the great update! We're happy that we were able to help you out. Let us know if we can help with anything else.
