I need to install a Lillangen high cabinet that has feet on the floor but as it's tall it needs to be secured with four screws. There is a stud I can use but I am scared of not screwing right into the middle of the stud and hitting a wire although I can't find any wires with my voltage meter on that wall. Everything I read about drilling into walls and avoiding wiring seems fairly vague.
Can I attach it using one stud and drywall for the other side? And do I need to use a molly bolt? Or an anchor or other kind of attachment? Is 1 1/4" enough or too long for wires? I'm still not sure about wires in drywall if I drill well away from the stud.
Would this kind of cabinet be safe to attach to only drywall since it has feet? Thank you.
Edited to show metal brackets to connect to wall.
