How to Choose Magnetic Catches

Magnetic catch by Monroe Engineering

Are you looking to buy magnetic catches? There’s no denying the fact that magnetic catches are a convenient latching mechanism. You can use them to open and close electronic enclosures, cabinets, drawers, vehicle components and other objects.

All magnetic catches consist of two separate parts. They feature a ferromagnetic plate as well as a larger and enclosed magnet. You can install the plate on a rotating object, such as a cabinet door, and you can install the enclosed magnet on the fixed object or surface to which it’s connected, such as the interior of the cabinet itself. Regardless of how you intend to use them, though, you’ll need to choose the right type of magnetic catches.

Check the Shape

Magnetic catches are available in different shapes, the most common of which is rectangular. Most magnetic catches have a rectangular-shaped plate and a rectangular-shaped enclosed magnet. The two parts will automatically pull together, thereby serving as a latching mechanism.

With that said, some magnetic catches have a cylindrical-shaped enclosed magnet, instead. Known as barrel-style magnetic catches, they are a great choice for small spaces. If you’re planning to use a magnetic catch on a small object where there’s a limited amount of space, you may want to choose a barrel-style magnetic catch. Barrel-style magnetic catches consume less space while providing the same functionality as rectangular-shaped magnetic catches.

Consider the Installation Requirements

In addition to the shape, you should consider the installation requirements when choosing magnetic catches. Most magnetic catches are installed with threaded fasteners. You’ll need to position each part, followed by driving threaded fasteners through the parts’ holes.

You can install most magnetic catches with screws. The number and size of the screws required for installation, though, may vary. Small magnetic catches typically have fewer, as well as smaller, through holes than large magnetic catches.

Metal vs Plastic

The material from which a magnetic catch is made may vary. Some of them are made of metal, whereas others are made of plastic. Plastic magnetic catches are lightweight, inexpensive and versatile. They still feature an enclosed magnet, but it’s covered in plastic.

Metal magnetic catches are heavier than their plastic counterparts, but they offer a superior level of strength and durability. They can withstand more use while simultaneously supporting heavier loads. Common metals in which magnetic matches are made include aluminum, brass and steel.
