SilverLine 2900 single hung windows

I'm afraid I can't confidently narrow down the hardware you need from the brand alone. SIlverline windows have been known to use the following tilt latches we carry here; and the T-Lock Shoe could be either our 15-195 Closed Cam or 15-195B Open Cam Shoe, as well as possible the 15-236 shoe, with the characteristic groove in the stem. But ultimately, you'll need to compare the dimensions and specifications of each item to your old hardware to see what matches best. Please send pictures of the hardware removed from the window if you are uncertain.
