tilt window lock





Thank you for posting and submitting your photos.
We'll get started with your spiral window balance. The original plastic cover you mention, do you have that nearby? If so, be sure to measure the diameter of of the cover (tube), as this will determine whether it is a 600 Series (5/8"), or a 900 Series (3/8"). Also, if you can, measure the length of the tube portion of your balance.

My initial reaction is that you will need a S600-27 (with blue tip option), however let's make sure we have the correct measurements before we proceed.
The latches shown above look similar to the 26-243 LH and the 26-244 RH latches. Take a look at the nose of the latch (the part that retracts in and out of the casing). Does this look similar to your original?




As for your latches, the 26-243 and 26-244 appear to be the closest match online. Compare the nose of the latch (the part that retracts in and out of the casing) to our product pictures. I cannot see the nose of your latch in your photos.
