M and w vinyl windows replacement patts

Hello,

It looks like you have an older block and tackle balance which is no longer available. We'll need to see an undamaged balance removed from the window to determine if there is a newer replacement option you could use. You will need to weigh the window sash as well to determine the spring strength your new balances will need. 

If you need a new sash lock as well, please provide us with the exact distance between the mounting holes, measured from center to center. Thank you!
