The installation should not be too difficult for average amateur craftsmen,
the biggest challenge is to drill the holes at the correct distance to the wall.
If the bracket at the end depends wrong that should apart from the optical flaw
not so tragic, the two holding arms can compensate definitely a slight imbalance.
WARNING: mounting material (plugs / bolts) are not included,
but certainly a recommendation for 6 mm plugs and screws with 50 mm length.
I had 40 mm screws at hand, but also the holding (at least in my wall) well enough.
The two supporting arms are sufficient and especially tight enough padding, I'm not afraid,
that the padding will dissolve very quickly in items.
The arms are not feathered, but remain (yet) in the open position when you manually
apart pushes. It then hangs a guitar, "grab" the two arms of itself.
The guitar hanging safe and stable on the wall with enough distance so that neither Wall
can still abkriegen guitar scratches or other injuries (in normal use).
=== === CONCLUSION
Conveniently, keeps stable and sure looks good - that's all I need.
In brief: Full points and full recommendation!
