Paul Sr. from SWISCO responded:
34" Series 350, 350-34, weight ranges:
3310 = 8 to 13 lbs.
3320 = 13 to 18 lbs.
3330 = 18 to 23 lbs.
3340 = 23 to 28 lbs.

This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
