herculite sliding door handle

Hello,

Our 82-030 can replace the handle set with the top-mounted thumb lever without adaptation. The reason for this is because both handle sets engage with the mortise using a spindle that's centered between the two screw holes.

What's confusing is that the original handle doesn't look like it has a centered latch since the thumb lever itself is, for whatever reason, mounted above both screw holes. The reality is that when that thumb lever is turned, an internal arm mechanism reaches down the spindle and turns it.

Our 82-030 works the same way but its thumb lever is centered already. It doesn't need that additional (and redundant) arm mechanism.
