Hanging heavy cabinets on metal studs can seem daunting, but with the right techniques and materials, it can be done safely and securely. Here is a comprehensive guide on how to hang heavy cabinets on metal studs.
Finding the Metal Studs
The first step is locating the metal studs so you know exactly where to attach the cabinets. Here are some tips for finding the studs:
- Use a stud finder. Electronic stud finders are the easiest way to locate the metal studs behind the drywall.
- Look for drywall seams. Screws are typically driven into studs, so check the drywall seams for screws to identify stud locations.
- Check for markings. Builders often mark the stud locations on the floor or ceiling. Look for these clues.
- Knock and listen. Tap along the wall and listen for a solid “thud” sound that indicates a stud.
- Use magnets. Magnets will stick to the drywall screws or nails driven into the metal studs. Glide a strong magnet across the wall to find them.
Once you locate the studs, mark their centers with a pencil so you know the exact points to install the cabinet hardware.
Choosing the Right Hardware
Hanging heavy cabinets requires using the proper hardware designed for the job. Here are the best options:
Heavy-Duty Toggle Bolts
Toggle bolts slip through the drywall and expand behind the wall, gripping the metal stud tightly. This makes them ideal for heavy objects. Choose toggles bolts rated to handle at least 50 lbs each.
Lag Screws and Washers
Lag screws actually thread right into the metal studs for incredibly solid strength. Using oversized washers helps distribute the weight. Get lag screws with coarse threads and make sure the heads are compatible with your wrench.
Hollow Drywall Anchors
Special hollow anchors are made to handle heavy loads on metal studs. The ribbed hollow design clamps tightly behind the drywall. Look for a minimum 50 lb rating.
For hanging a heavy cabinet, use at least two of these heavy-duty fasteners attached to different studs to distribute the weight. More fasteners may be needed for extremely heavy cabinets.
Installing the Hardware
Follow these steps to securely install the hardware on the metal studs:
- Drill holes in the center of the studs at the desired height to hang the cabinets. For toggle bolts, the holes should match the bolt size. For lag screws, the holes should be slightly wider than the screw diameter.
- Insert the toggle wings into the holes and flatten them by pushing the bolts through the holes. Or drive the lag screws into the studs so they grip tightly.
- Slide any washers onto the toggle bolts or lag screws. Position them so they’ll be against the cabinet bracket or cleat.
- Hold the cabinet or cleat in position and insert the toggle bolts or lag screws through the hanging holes to attach it against the wall.
- Tighten the bolts or screws securely. Do not over tighten lag screws or you may strip the threads in the stud.
Hanging the Cabinets
Once the hardware is securely installed in the studs, you’re ready to mount the cabinets. Be sure to follow all safety precautions when lifting heavy cabinets. Here are some tips:
- Attach strong brackets or cleats to the back of the cabinet to screw into the toggle bolts or lag screws.
- Lift and position the cabinet against the wall, lining up the bracket holes with the hardware.
- Insert bolts through the bracket into the toggles or screws. Hand tighten nuts then use a wrench for final tightening.
- Level and adjust the cabinets, then tighten all hardware completely. Periodically check for any loosening over time.
- For extremely heavy upper cabinets, consider using ledger boards attached to multiple studs to support them.
- Use filler panels or soffits above the cabinets to close any gaps between them and the ceiling.
Safety Tips
- Use helpers and equipment like dollies or lift tables when moving heavy cabinets to avoid injury.
- Work safely on ladders or scaffolding when installing upper cabinets. Never lean a ladder against the cabinet.
- Wear safety glasses when drilling and installing hardware. Bits and fasteners can break or fall.
With the proper hardware selection and installation techniques, you can safely and securely hang heavy cabinets on metal stud walls. Just be sure to attach to multiple studs and use fasteners strong enough for the load. This allows your cabinets to support even the heaviest contents without pulling off the wall.
Frequently Asked Questions About Hanging Heavy Cabinets on Metal Studs
What type of hardware is best for installing heavy cabinets on metal studs?
For metal studs, choose heavy-duty hardware like toggle bolts or lag screws that can grip the metal securely. Hollow drywall anchors also work well. Be sure to select hardware rated for the cabinet weight.
How many fasteners should I use?
As a minimum, install at least two fasteners attached to different studs for each heavy cabinet. Larger cabinets or those weighing over 100 lbs may require additional hardware. Spreading the weight across multiple studs is key.
What if a cabinet spans two metal studs?
If the cabinet width exceeds the 16” or 24” stud spacing, attach a horizontal wooden ledger board to both studs, then install the cabinet on the ledger. This transfers the weight across multiple studs.
Should I attach the hardware to the top or bottom of the studs?
Attach the fasteners near the top of the metal studs. This reduces leverage from the weight “pulling” on the fasteners. Studs are strongest near the top and weakest near the bottom.
How do I find the metal studs behind drywall?
Use a stud finder, check for drywall seams, look for markings on floor/ceiling, tap and listen for solid sound, or use magnets to find screws/nails driven into studs through the drywall.
Can I just use drywall anchors?
No. Plastic drywall anchors do not work well on metal studs. The hardware needs to mechanically grip the stud, so stick with lag screws, toggle bolts, or hollow drywall anchors made for metal.
Conclusion
Installing cabinets on metal stud walls is completely doable with the right techniques. Be sure to find the studs, choose hardware designed for metal, and attach the cabinets securely into multiple studs. Follow all safety advice when working on ladders and lifting heavy objects. With robust fasteners properly anchored into the stud framing, you can gain full use of your sturdy metal stud walls for mounting cabinets that will last a lifetime.
