Contact SWISCO Tilt Latch Help

I am sending a picture of the part needed for Certain Teed window tilt latch to you in a separate e-mail as the owner has the picture. These pieces are from Certain Teed windows and have no information on them. A company called MI told me to email Swisco. I believe these are tilt latches but was just given the part. We need 9 (pairs) of them and would appreciate any help with this. Terry
