Thanks for contacting us! You can actually look up the proper option on each balance's respective store page. We have a chart on each page telling you how much weight each option supports.
For the 30" balances on both the 16.5 pound and 19 pound sashes, I recommend the 30B option in each case. For the 26" long balance on the 19 pound sash, I recommend the 26B option. Finally, for the 36" long balance for the 28 pound sash, I recommend the 36D option. |
