Agree that the sliders use oem style gaskets not a special gasket for installation.

Thanks Ray! Just tucked it in for the season. Six month hibernation

Kirk, those are in my single wall top. Here’s my take on single pane sliders in 1x wall tops. The window frame “spine” that rests inside the gasket is thicker than that on double pane sliders. Thickness is similar to that of 2x wall glass. Based on my experience installing 2x wall glass into a single wall top your single pane sliders should go in without having to trim the top. You might expect some slight gasket corner wrinkle but I suspect that about it.
