Hi. I'm purchasing the 34" SERIES 385 CHANNEL BALANCE and I'm not sure which stamp option to go with. The sash weighs 27.6 lbs so not sure if I should go with the 3340 (23 to 28 lbs) or 3350 (28 to 32 lbs). Appreciate your recommendation.
Thanks,
brett

Hey Brett. If the sash weighs exactly 27.6 lbs go with the stamp option of 3340, which covers a window sash in the weight range of 23 through 28 lbs.
