sash release lever, plastic side channel pivot shoe?

Question

These are circa 1997 Mastic Inner-lok Vinyla Replacement windows. None of the parts you show match up exactly, but do you have parts that will work?

I see some sash release levers that are close.
Not sure about the pivot shoe, or if I have even identified that properly.

Thanks so much

For your Mastic window, the pivot shoe is 15-175, and it uses Series 152 coil springs. You will need the spring weight number on the old spring when ordering.

Most Mastic windows use 58-127 wool pile weatherstripping, but there's no guarantee. Again, you will need to compare sizes. If that's not right, send a photo of the cross-section of your weatherstrip, as shown at the bottom of the post.

Finally, the top tilt latch is no longer available, so we suggest a top mounted tilt latch like 26-195 and 26-196, screwed on with 33-090 screws. See our media guides on the right for more.
