6 Best Magnetic Catches For Holding Shutters Open In High Winds

High winds can turn a simple set of barn or shed shutters into dangerous, flailing projectiles that threaten siding, glass, and nearby livestock. Secure hardware is not just a convenience; it is a fundamental requirement for maintaining a functional and safe farm structure. Choosing the right magnetic catch ensures those shutters remain pinned against the exterior wall, even when the wind whips across open pastures.

ShutterLok Magnetic Catch: Best for Classic Style

The ShutterLok system provides a refined, traditional aesthetic that complements wooden barn shutters without appearing overly industrial. Its design focuses on a low-profile installation that sits flush against the surface, ensuring the magnet does not interfere with the natural swing or aesthetic appeal of painted timber.

This option works exceptionally well for smaller outbuildings where hardware visibility matters. It relies on a strong, reliable pull that keeps shutters steady during light-to-moderate gusts.

Choose this unit if the primary goal is maintaining the visual charm of a heritage-style shed. While it lacks the sheer brute force of heavy industrial magnets, its elegance is unmatched for cosmetic-focused renovations.

Jiayi 40 lb Magnetic Catch: Top High-Wind Pick

When storm season brings gale-force winds to the farm, standard hardware often fails. The Jiayi 40 lb Magnetic Catch offers the necessary holding force to keep heavy, weather-treated shutters firmly locked against the building’s exterior.

The high weight rating ensures that the shutter remains stationary, preventing the repetitive slamming that eventually compromises hinges and trim. This magnet is built to endure the elements, with a rugged housing that resists premature cracking or deformation.

If the farm sits in an exposed area prone to frequent, high-velocity wind events, this is the definitive choice. It is overkill for a sheltered garden shed but essential for primary barn doors or shutters facing open fields.

Lizavo Heavy-Duty Latch: Most Versatile Option

Versatility on a farm often means finding hardware that adapts to various mounting surfaces, from rough-hewn cedar to smooth composite siding. The Lizavo Heavy-Duty Latch features an adjustable design that helps bridge the gap between the shutter and the wall, which is often uneven on older structures.

This latch functions as both a physical guide and a magnetic anchor. It provides the mechanical stability necessary to prevent lateral shifting during heavy storms.

Consider this option when working with older, non-standard shutters that do not sit perfectly flat against the wall. It offers the best compromise between rigid mounting and ease of alignment.

National Hardware V338: Easiest to Install

For those balancing daily chores with structural repairs, the National Hardware V338 is the ultimate time-saver. Its straightforward, surface-mount design allows for rapid installation using standard tools, making it ideal for quick fixes before a forecasted storm.

The hardware is widely available and standardized, meaning replacements are easy to source if one is damaged by a stray piece of equipment or heavy debris. Reliability is high, and the mechanism is simple enough that maintenance is virtually non-existent.

This is the go-to choice for the practical farmer who needs a reliable, no-nonsense solution without the need for complex alignments. It is a workhorse that does the job without demanding significant investment or labor.

Neodymium Bar Magnet Set: A Strong DIY Solution

Hobby farmers often need custom solutions for unconventional shutter configurations or recycled materials. Purchasing a set of high-grade neodymium bar magnets allows for a completely bespoke approach to securing shutters.

These magnets possess an incredibly high strength-to-size ratio. When housed in custom-built steel brackets or recessed into the wood, they offer a clean, invisible hold that standard store-bought latches cannot replicate.

Use these only if comfortable with light fabrication and precise measurement. They represent the most robust and discreet hold available, provided the user is willing to put in the time to install them correctly.

JQK Magnetic Door Stop: Best for Ground-Level Use

Sometimes, the best way to secure a shutter is to anchor it to a low-profile floor mount rather than the wall. The JQK Magnetic Door Stop serves this purpose perfectly, utilizing a powerful magnetic engagement that prevents the shutter from swinging outward.

This approach is particularly effective for large, heavy shutters that are difficult to pin to the wall surface. By pinning the bottom corner of the shutter to a stake or concrete base, the structural stress on the hinges is significantly reduced.

Choose this style if top-heavy shutters are prone to bowing or if the siding cannot support the weight of a standard wall catch. It provides a secure, ground-anchored point that is remarkably resistant to high winds.

How to Pick the Right Magnet Strength for Wind

Selecting the correct magnet is a matter of physics rather than preference. A lightweight decorative shutter requires only a 5-10 lb pull, while a heavy, solid-wood storm shutter requires 40 lb or more to prevent movement during gusts.

Always account for the leverage exerted by the wind. A wider shutter acts like a sail; even a modest breeze can generate enough force to overcome a weak magnet.

• Lightweight Vinyl: Use 5-15 lb magnets.
• Standard Wood/Composite: Use 20-30 lb magnets.
• Heavy Timber or Large Shutters: Use 40+ lb magnets or multiple contact points.

Installation Tips for a Secure Shutter Hold

Alignment is the single most important factor in magnetic performance. If the magnet and the strike plate do not meet perfectly flat, the holding force drops by more than half, leaving the shutter vulnerable to rattling.

Ensure the surface is level before screwing in the hardware. Use shims if necessary to create a perfectly flat mounting plane, and always use stainless steel screws to prevent the hardware from seizing or pulling out due to wood rot.

In high-wind areas, apply a thin bead of exterior-grade adhesive behind the magnet base for added stability. This prevents the hardware from twisting over time, ensuring the magnet stays aligned with the strike plate throughout the changing seasons.

Preventing Rust on Your Outdoor Magnetic Catches

Farm environments are harsh; moisture, manure dust, and seasonal temperature swings create the perfect conditions for corrosion. Always opt for marine-grade stainless steel or powder-coated finishes to extend the lifespan of magnetic catches.

If using standard hardware, apply a light coat of clear exterior-grade lacquer or a marine grease to the contact surfaces. This creates a barrier against moisture and prevents the magnet from bonding to the strike plate due to light oxidation.

Periodically inspect the hardware during routine seasonal barn checks. A quick wipe-down with a damp cloth can remove corrosive dust and debris before it has a chance to damage the finish.

Frequently Asked Questions About Shutter Magnets

Will these magnets hold during a hurricane? No, magnets are meant for sustained high winds, not extreme storm events. During a hurricane, manually latching shutters with physical barrel bolts is the only safe procedure.

Can magnets be painted to match the barn? Yes, but use a thin coat of spray paint. A thick, uneven paint layer creates a gap between the magnet and strike plate, which drastically reduces holding power.

Do magnets lose their strength over time? High-quality neodymium magnets maintain their strength for decades under normal farm conditions. If a magnet suddenly loses its hold, it is almost always due to misalignment or debris buildup rather than a loss of magnetism.

A little investment in the right magnetic hardware now saves the frustration and expense of repairing damaged shutters later. Choose a system that matches the weight of your shutters and the intensity of your local weather to ensure your farm buildings stay secure through every season.
