The window I am working 0on has 2 springs that both attach to what appears to be your 15-150D standard support. One mounted directly above the other. One spring is 3.5 pound and the other is 5.5 pound. The video on your site only shows installation of a single spring unit. Should I change over the window to your double carrier and what is the best configuration of spring weight 3.5 on top or 5.5.
Specifically,
1. Can I use the 15-150D on the window?
2. Does it matter which spring is placed where? 3.5 on top or 5.5 on top?
3. I assume I would be buying 2-3.5 and 2-5.5 pound springs to replace both sides.
4. One of the broken springs shows that they are 33" your site sells 35" will the different length present any serious issues regards closing properly?
