Product Description
The CMS Magnetics Universal Heavy-Duty Magnetic Latch provides an uncompromising 50 lb direct breakaway holding power, engineered to secure heavy swinging doors, pantry closures, industrial equipment access panels, and mobile RV cabinetry. Encased inside a heavy-gauge stamped steel channel housing with an impact-resistant ceramic ferrite magnet core, this latch assembly eliminates sagging, warping, and accidental blow-outs where standard hardware catches fail.
Each unit includes a heavy-duty, zinc-plated matching steel strike plate pre-machined with dual countersunk screw holes for fast, flush mounting against natural wood, composite MDF, drywall studs, or structural sheet metal.

Need a Lighter Catch for Standard Indoor Cabinetry?
At 50 lbs of direct pull force, this latch is built for heavy-duty doors and high-vibration applications. If 50 lbs exceeds your door weight or requires too much opening effort for daily kitchen or vanity use, view our 25 lb pull countersunk magnet for cabinets, designed specifically for standard residential cabinet doors, smaller lockers, and furniture stiles.
Primary Engineering & Commercial Applications
- Heavy Interior & Exterior Doors: Commercial pantry doors, solid oak entries, screen doors, and sliding partition stops that require positive mechanical retention without latch handles.
- RVs, Motorhomes & Marine Galleys: Prevents overhead bins, heavy cookware drawers, and storage compartments from flying open during rough road travel or boat motion.
- Industrial Enclosures & Machinery Guards: Fast, non-mechanical magnetic latching for CNC chip guards, electrical cabinets, and filter inspection access panels.
- Workshop & Tool Storage: Keeps heavy wooden tool chests, garage supply lockers, and metal utility cart doors securely shut under heavy tool vibration.
Safety & Installation Warnings
- Severe Pinch Hazard: With 50 lbs of holding force, the latch and striker plate snap together with high speed when brought within 1 to 2 inches. Keep fingers and hands away from contact faces during alignment and test closures.
- Flush Fastener Alignment: Use 82° flat-head countersunk screws. Ensure screw heads seat fully beneath the outer steel rim on both the latch body and the striker plate. Protruding screw heads create an air gap that reduces rated holding force.
- Lever-Arm Placement: Mount the latch as close as possible to the opening door handle. Placing the latch near the hinge line drastically multiplies the opening pull required, risking damage to door frames or mounting screws.
- Medical Implant Safety: Keep static magnetic assemblies at least 12 inches away from pacemakers, ICDs, and magnetically sensitive electronic equipment.
