Hello,
We'd be happy to look into this for you but the latch shown in your photo is too damaged to identify. We would need to see an intact latch from the other side or an identical window to compare to our inventory. We'll also need you to write-out the exact distance between the center of the installation holes to narrow down your options. Thank you!
Thanks for getting back to us. We carry two latch pairs with 2-1/8" hole spacing, which we've related on this page for you to review. Look over the dimensions from our product page below to confirm if one of them matches your original latch.
Thanks for getting back to us. It looks like you have spiral balances like the (3/8") S900 or (5/8") S600. See the 75-006 tool used for installation and to charge the balances. See the videos related on this page to assist you.
Note that the charging tool is currently back ordered but you can also use a pair of needlenose pliers to grasp the spiral and change the replacement balances if you're on a time crunch.
