Magnetic Door Catches

Heavy-Duty Magnetic Door Catches & Cabinet Latches

Magnetic door catches hold a door closed with magnetic force instead of a mechanical latch, which means no moving parts to wear out and no roller or spring to replace.

Rochester Magnet supplies magnetic door hardware to cabinet manufacturers, contractors, OEMs, facility teams, and homeowners who want a quiet closure that keeps working after tens of thousands of cycles. Order stock catches or send us a specification, and we will build a magnetic latch for doors sized to your product.

How a Magnetic Door Catch Works

Every magnetic door catch has two halves:  

  1. The catch body, which houses the magnet, mounts to the frame or cabinet interior. 
  2. The strike plate, a piece of ferrous steel, mounts to the door itself. 

When the door swings shut, the magnet pulls the plate against it, holding the door in place until someone applies enough force to break the connection. Holding force comes from the magnet material and the contact between the two faces. 

A catch reaches its rated strength only when the strike plate sits flush against the magnet with no gap. Even a small offset from a misaligned hinge or a thick coat of paint reduces the hold.

Some designs go a step further. A touch latch adds a spring mechanism so a light push releases the door, which is useful on handleless cabinetry. Concealed catches mount inside a bored hole, so nothing shows when the door is closed.

    Advantages Over Traditional Latches

    Roller catches, ball catches, and friction latches all rely on parts that rub, compress, and eventually fail. Magnetic cabinet latches avoid that problem:

    • No mechanical wear: With nothing to compress or slide, a magnetic catch holds the same force in year 10 as it did on day one.
    • Quiet operation: There is no click or snap when the door closes, which matters in offices, healthcare settings, and residential kitchens.
    • Forgiving alignment: A magnet pulls the door into position across a small gap, so slight settling in a frame does not stop the door from closing properly.
    • Clean appearance: Concealed and low-profile options keep hardware out of sight, which architects and furniture designers tend to prefer.
    • Simple installation: Most catches need two screws and a strike plate, with no mortising or adjustment mechanism to set.

    Magnetic hardware also handles doors that other catches struggle with, including glass doors with adhesive-mounted plates and doors that need to be openable from either direction.

    Magnet Materials and Pull Strengths

    The magnet inside the housing determines what a catch can hold and where it can be used.

    Magnet material:

    Typical pull range:

    Best for:

    Ceramic (ferrite)

    3 to 10 lbs

    Light cabinet and closet doors, cost-sensitive volume

    Alnico

    8 to 20 lbs

    Channel-mount catches, higher-temperature settings

    Neodymium (rare earth)

    15 to 100+ lbs

    Heavy doors, compact housings, industrial enclosures

    Ceramic and alnico catches cover most residential cabinetry, where a few pounds of hold is plenty for a lightweight door. Neodymium makes a heavy-duty magnetic door catch possible in a small body, since rare-earth material produces roughly five to seven times the force of ceramic at the same size. That strength lets a concealed catch hold a solid-core door without a visible housing. 

    Published pull ratings assume ideal conditions. In practice, plan for a real-world hold to come in below the rating, and size the catch with a margin above what the door actually needs.

    Housings, Coatings, and Corrosion Resistance

    Housing material decides where a catch can be applied:  

    • Nylon and ABS bodies suit dry interior cabinetry and keep costs down at volume. 
    • Steel and zinc-plated housings add durability for commercial and industrial use. 
    • Stainless steel is the choice anywhere moisture is present, which is why marine and RV builders specify it almost exclusively.

    The magnet itself needs protection, too. For washdown areas, salt air, or outdoor enclosures, ask us about a sealed housing with a coating rated for the exposure.

    Magnetic Catch Mounting Options

    How the catch attaches influences both the look and the installation time.

    • Surface mount is the standard for cabinets. The body screws to the frame or shelf, the plate screws to the door, and installation takes a couple of minutes per door.
    • Concealed and press-fit catches drop into a bored hole so the hardware disappears when the door shuts. Common on fine furniture, display cases, and architectural millwork.
    • Adhesive mounts work where drilling is not an option, such as on glass, laminate, and finished panels. Pressure-sensitive adhesive backing bonds the magnet or plate directly to the surface.
    • Channel and cup mounts encase the magnet in a steel channel or cup that focuses the field toward the strike face, increasing the effective hold of the same magnet.

    Custom assemblies are available when a stock housing does not fit your product. We build magnetic assemblies to your drawing, including overmolded, threaded, and countersunk configurations. Our countersunk neodymium magnets are a common starting point for OEMs who want to screw a magnet directly into a door panel.

    Installation Considerations for Magnetic Latches and Catches

    There are a few details that separate a catch that holds for a decade from one that gets replaced.

    1. Set Alignment First: Mount the catch body, close the door, and let the strike plate find its own position before you drive the second screw. Most plates have slotted holes for exactly this reason.
    2. Account for the Gap: Pull force drops sharply as the distance between the magnet and plate grows. A gap of even one sixteenth of an inch can cut hold significantly.
    3. Match the Plate to the Magnet: A thin or undersized strike plate saturates and wastes available force. Use the plate supplied with the catch, or specify a thicker steel plate for high-force applications.
    4. Consider the Door Weight and Swing: A tall door with a long lever arm needs more hold at the latch point than a small cabinet door of the same weight.
    5. Plan for Temperature: Standard neodymium loses strength above roughly 80°C. Near ovens, engines, or process equipment, specify a high-temperature grade or an alnico catch.

    Applications for Magnetic Door Catches by Industry

    The same basic hardware shows up in very different settings, and each one puts its own demands on housing material, pull strength, and mounting style. Here’s where magnetic door catches are most commonly needed.

    Cabinetry and Furniture

    Magnetic cabinet door catches are the default closure for kitchen, bath, and office casework. Furniture manufacturers buy them in bulk to maintain a consistent feel across a product line.

    Residential and DIY 

    Homeowners use cabinet door magnets for closet doors, pantry doors, built-ins, and pieces they build themselves. Installation needs a drill and a screwdriver.

    Commercial Construction 

    Contractors and facility teams specify magnetic door hardware for access panels, casework, millwork, and utility doors where a quiet, low-maintenance closure keeps service calls down.

    Industrial and Manufacturing

    An industrial magnetic door catch secures equipment enclosures, control panels, machine guards, and inspection doors. Sealed housings hold up to dust, vibration, and washdown.

    Marine 

    Boat builders use stainless catches on cabin doors, lockers, and hatches, where salt air destroys conventional hardware, and a door swinging loose in rough water is a hazard.

    RV and Transportation 

    Vibration is the enemy in a moving vehicle, and a magnetic door latch has no spring or roller to shake loose. RV manufacturers use them throughout cabinetry, storage compartments, and interior doors.

    OEM Product Design 

    Manufacturers integrate magnetic closures into appliances, kiosks, medical carts, vending equipment, and consumer products. We work from drawings and prototypes through production volume.

    Frequently Asked Questions About Magnetic Door Hardware

    Not under normal use. A neodymium or ceramic magnet kept within its temperature rating loses a fraction of a percent of strength per decade. Catches that stop holding have almost always developed an alignment problem, a debris buildup on the strike face, or a loose mounting screw rather than a weak magnet.

    Standard catches are not. A child can pull most cabinet catches open. For cabinets holding cleaning chemicals or medication, use a purpose-built magnetic safety lock, which uses a hidden magnetic key to release an internal latch and works on a different principle than a holding catch.

    The fields around a typical cabinet catch fall off quickly with distance and pose no risk to phones, laptops, or modern credit cards at normal handling distances. Anyone with a pacemaker or implanted defibrillator should keep a safe distance from strong rare earth hardware, and manufacturers integrating high-force magnets near sensitive instrumentation should test for interference during design.

    Yes. Wood, aluminum, glass, and plastic doors all work fine because the strike plate supplies the ferrous material. The plate mounts to the door with screws or adhesive, and the magnet only needs to contact that plate.
