Finally assemble without "3rd hand"

Already 2 Mini-Levels For socket outlet and switch assemblies.
For the first - without magnetic holder - you need a 3rd hand.
The second - although with magnets - slip during the screwing (fixing of the insert).
Now I am very happy with the Stabila spirit level 17775th
+ At the back is to your one stop to keep them safe position on the support ring edge of the insert.
+ The strong magnets rear prevent slipping on the support ring,
while the claws tightened.
+ Through a practical recess bottom and the screw on the support ring is possible.
Strong buy recommendation !!!
