1: I am converting from a Block and Tackle Rod Balance to a Channel Balance for all my windows, 19 to be exact. Does it matter which cam is chosen, open or closed, when replacing the entire balance? How do I know if the existing pivot bars are compatible with the replacement balances? Should I just replace the existing pivot bars with new pivot bars that are compatible with the new channel balances? The width of the existig shoe is 1 1/4"and they are "open", but that is the crossbow system.
2: Second floor windows have a 22 1/2" block and tackle rod for the balances. so, I probably would order a 22" channel. But the weight of these windows is 18.6 lbs. What is the stamp option for this sash weight? B or C ?
3: First floor windows have a 34 1/2" block and tackle balance. But I have to get back to you with the weight of these windows (probably a "c" stamp for the sash weight). The width of these windows are 36", can I weigh just one window and presume they are all the same weight? All sashes are the same dimension in height and have a 34 1/2" block and tackle balance as well.
4: Last question for now: One of the windows have a cracked/split frame where the pivot bar is attached. It is actually on the verge of detaching from the frame itself. Is there any reinforcement you offer for this situation?
Thank You,
Rossio
