These mounts are super flat, only 33.5 mm deep, & have security lock features that work effectively in the small space between the display & the wall. Vogel’s new professional 5000 series wall mounts offer high levels of theft protection for flat displays used in public areas that cannot be continually supervised. This is a versatile product line that provides extra features for theft prevention & quick & easy installation. A sturdy lock secures displays effectively & very closely to the wall to prevent removal. These mounts have a clean & elegant look & take up a minimum amount of space, yet making the display easily accessible for display service. The unique built-in levelling function in the wall plate makes life a lot easier for installers. It helps them to correct the levelling during installation.
