General characteristics
Fitting the EROUND boxes
The new EROUND line boxes by Pizzato Elettrica feature 4 additional 
holes in the cover, which make it possible to fit the boxes to a wall 
by inserting the screws through their external part, therefore without 
needing  to  open  their 
cover  to  gain  access  to 
the holes.
The  wall-fitting  screws 
and the box cover closing 
screws can be sealed by 
means  of  4  caps  (caps 
supplied  with  the  box) 
which, besides improving 
the  appearance  of  the 
box  line,  avoid  any  dirt 
being  deposited  inside 
the  screw  recesses  and 
make tampering more difficult. 
External fitting turns out to be particularly advantageous for prewired 
boxes, since the entire installation work becomes simpler; all that is 
needed is to fix the box and attach the connector which, thanks to the 
cable inlets available on the four sides of the box, can be positioned 
in the chosen direction.
