Hello, We'd be happy to help but we would need you to write out the exact distance between the installation hole centers of your lock and keeper to compare to our inventory. As for your balance hardware, It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. 
Comparison of the S351 and S390 balance shoes.
You'll also need to locate the numbers stamped on the balance channels to choose the corresponding strength opinions from the chart listed under the balance product description. As for the takeout clips, see the 16-002 below. You're also welcome to look through our selection of fasteners here. Thank you!

Great, then you would need the S351-21 balances with 2040 strength options. You will also need to check the stamp on your 15" balances to choose the corresponding strength option on the S351-15 product page. As for the sash lock, unfortunately, we do not carry an exact match but we do carry a few similar options with 2-1/16" holespacing. I would recommend starting by reviewing the dimensions of the 90-161 and 90-278 below. A key detail would be how the installation hole backsets compare to yours.

We've also related the 90-301 and 90-237 face-mounted keepers with 1" hole spacing on this page for you to look over. Just let us know if you have any other questions. |
