positive:
- A very wide range of screws for fixing all kinds of boxes
- The holders are stable
- If you still want the same lay cables through an opening behind the holder is the material to work very well for a possible wider opening or another
prepare opening itself
negative:
- Only the screw with which the box is aligned and fixed could be something "catchy"
(Is a Phillips screw, but unfortunately very flat, but goes just well using a flat screw driver, if the box is anchored to maximum height)
Conclusion:
great product, I would buy again at any time
ps gave despite the screw 5 stars, as one the box Changes frequently do not, or do not have their box will anchor at maximum height
