Hello
I'm in need of (2) 15-102 double side load carriers and (4) 145-6 springs.
My original springs have no slot, just a step. One has a 6 stamped on it, the other one has no # on it. What do you suggest I order for the second spring? And, is your slotted spring compatible with my step-only spring?

Hello, thank you for posting,

To further review, are you able to show us pictures of the original coil springs and housing? To determine the correct weighted coils, please provide the weight of the window sash to move forward. The sash will need to be removed and placed on a bathroom scale. Thank you!
