Help with Alenco Window Parts

Thanks for posting. The tilt latches look like our 26-157 and 26-158. The silver part is called a balance; yours in particular is a spiral type balance. Since this is a tilt window then you only have two options to pick from: either the 3/8" diameter Series 900 or the 9/16" diameter Series 600. Look these over and let me know if you had any questions!
