Magnetic Door Stopper, Stainless Steel (up to 4 kg, Heavy-Duty)

This magnetic door holder model is built with increased magnetic power to service heavier doors and lids on the boat. With a capacity of up to 4 kg, it is a stronger variant suitable for the hefty cockpit door to the salon or a heavy deck hatch, for example. Like the smaller version, the set includes a stainless steel magnet component and a matching metal plate. The magnet firmly “locks” onto the plate upon contact, holding the door securely open until you decide to release it. This prevents the door from slamming shut due to a sudden gust or a change in the vessel’s angle. The reinforced holder is made of corrosion-resistant steel, allowing for installation outdoors – for instance, on a wheelhouse door or companionway hatch that is often kept open. The magnet’s base plate is robust and can be firmly attached with screws to fiberglass, wood, or metal.

• For Heavier Doors: Perfect for large yacht doors – the main cabin entry, captain’s cabin door, or other substantial openings. It will not let a heavy door swing closed unexpectedly, thanks to its stronger magnetic grip.
• Stability Under Way: In choppy seas or if the boat tilts, this stopper will hold the door open. Especially useful during maneuvers or when people are moving through the doorway – the door won’t swing unpredictably.
• Professional Quality: The materials used are marine-grade – the stainless steel won’t rust, and the magnetic mechanism is sealed for protection. This ensures long service life, even if the unit is exposed to rain and salt spray.
• Universal Design: Despite being more powerful, the holder remains relatively compact and unobtrusive. It can be paired with the lighter model for different doors on board – lighter doors with the 3.5 kg version, heavier doors with the 4 kg version, for a complete solution.
