Pre-drill to avoid cracking the plaster and fix into the studs; plaster anchors are weak for heavy panels.
Panel weights
| Panel | Approx. weight |
|---|---|
| 24 × 48 in, 1 in | 6 lb |
| 24 × 48 in, 2 in | 10 lb |
| 24 × 48 in, 4 in | 18 lb |
| 48 × 96 in, 2 in | 40 lb |
Choose anchors rated for at least four times the panel weight. Z-clips let you lift a panel off later for cleaning or repainting.
Before drilling, check for wiring and pipes with a detector, and never drill fire-rated walls without confirming the penetration is allowed.
