left handed roller nut?

Digging around the interwebs I found this chunk of info on the LSR:
"The nut is designed to work only on right handed guitars - There is no left hand version."

The ABM 7020C roller nut appears to be symmetrical (based from the pictures).
If it's staggered you may be able to turn it the other direction for your uses.
Here are 3 sources. One of the reviews says they're all the same size.

That's an interesting part, but I don't see any way of fastening it or adjusting height. I went in search of engineering drawings, but no joy.

Is there any reason that the lsr roller nut cannot be installed upside down to cater for lefties?
 
There are several reasons. See here...

LSR nut view from tuner side

First, you have rubber dampers on the tuner side. If you flip it around, you'll damp the strings on the playing side.

Second, the slots the strings feed through are spaced for right-handed stringing. That is, low E on top, high E on the bottom.

Third, the strings rest in the "V" created between the bearings, which aren't centered on the block. You could compensate for this when you cut the slot for the nut, but it'd be risky business.

Finally, the mounting screws are also offset to the tuner side. You could compensate for this on a new install, so it's not a deal-breaker. Just something else making it non-symmetrical.

You may want to look at Graphtech nuts. They're not the ultimate part the LSRs are, but they're pretty slippery. If they're well-cut, string hangups aren't an issue. Also, don't install string trees. They're only necessary if you have a poorly made nut.
