Looking for a replacement spline for my cabinets
There are dozens and dozens (hundreds? thousands?) of types and shapes of &quot;spline&quot; material.
I recommend that you do NOT go on a &quot;goose chase&quot; for an exact duplicate of what was installed previously. Instead, I recommend that you take a door and glass pane with you to a local window/door/glass shop and find any alternative that will adequately secure the glass. There are even newer foam strip materials that conform to a variety of channel sizes and shapes. You could even consider &quot;non-spline&quot; alternatives like nailed wood strips or plastic clips.

it does not matter what the labeled use of the spline is, as long as it securely holds the pane
