Reinforcing wall cabinets when studs are hard to locate

[DarkKnight]

What are some reliable ways to reinforce wall-mounted cabinets to prevent sagging or loosening over time, especially when it’s hard to locate studs?

To reinforce wall-mounted cabinets and prevent sagging or loosening, toggle bolts or molly bolts are effective when studs are hard to locate, as they can support weight without needing to attach directly to the studs. Another option is adding a plywood backing to the cabinet, which helps distribute the weight more evenly. Whenever possible, securing the cabinet into multiple studs provides the most reliable support. Corner braces or cabinet brackets can also add extra stability.
