clock 13 minutes | 09 Apr 2021

Outdoor cabinet

Outdoor cabinets have specific requirements to stand up to the elements and the threat of vandalism or theft. This goes for whatever cabinet you’re designing, whether an industrial cabinet, outdoor electrical enclosure, telecom cabinet or cable junction box.

To help make your job easier, we’ve put together this guide to help you design your cabinet. We’ve made free CADs of our solutions available for download. You can also try before you buy on most products by requesting free samples.

Keep in mind that just as outdoor enclosures vary, so too can the location of components within the enclosure. This is a general guide for the components outdoor cabinets typically require. For example, an outdoor telecom cabinet will often have a rear door, so you might need to mount solutions on the roof or side panels to allow the door to open with ease.

Protecting your outdoor cabinets

Outdoor cabinets can be vulnerable to tampering and vandalism, so it’s good to know that we offer solutions that meet DIN V 1630:1999-04. Some of our access hardware components are also certified to WK2 standard. This means they’re tested for protection against physical force and the use of small tools, such as screwdrivers.

Environmental factors are another concern. We’ve addressed these issues with our own internal testing facilities, ensuring that components are robust and durable enough to resist the corrosive effects of salt spray.

NEMA and IP ratings

The first issue you need to be aware of is NEMA or IP ratings. Both of these are standards that tell you the level of protection against dust, dirt, moisture, water and other foreign objects, such as tools or fingers. If you want an outdoor NEMA cabinet, or one that is IP rated, then some of your components need to carry this rating as well. This will maintain your cabinet’s rating. You can learn more about IP and NEMA ratings here.

Fibre-optic cabinets If your application is a fibre street cabinet, the components shown here are suitable, from outdoor cabinet hinges to electrical enclosure locks and latches. However, you’ll also need fibre-optic cable management, designed specifically for optimising network performance and enabling easy access for maintenance. View components designed for fibre cabinets here.

Ideal components

Let’s look at the different parts attached to the frame, and what components you need to consider.

Outdoor cabinet doors

Front or rear door

If you want to access your electric cabinet design from both sides, then these components work for either front or rear doors.

Hinges

There are many different types of cabinet hinges. For an outdoor cabinet, your priority should be to prevent tampering. These outdoor cabinet hinges will help keep the equipment housed in your outdoor cabinet safe and sound.

Screw-on concealed hinges

Concealed hinges are installed inside telecom street cabinets and other enclosures, which provides extra security. Screw-on concealed hinges are ideal as electrical cabinet hinges, and come in three different materials: nylon, steel and stainless-steel hinges. The steel versions offer handed, pin, removable pin and spring-loaded options. If you need heavy-duty steel hinges, choose the pin version which has a 110˚ rotation angle and high mechanical strength. The handed versions with a 90˚ rotation angle are also great for heavy-duty applications as well as lightweight needs. Weld-on concealed hinges are also available.

Position-control hinge

A position-control hinge is a type of adjustable torque hinge and ideal for telecom roadside cabinets and other electrical panel enclosure designs. Made of nylon, it comes in a variety of different external mounting versions. These adjustable torque hinges have internal resistance and restrict movement of your panel or door. Adjustable torque position-control hinges are especially helpful for an outdoor electrical box enclosure, where frequent access is needed.

​Weld-on bullet hinges

Weld-on bullet hinges are ideal industrial cabinet hinges. They offer a high degree of security and strength, which is why they’re popular for outdoor applications, from industrial storage cabinets to specialty vehicles. Weld-on bullet hinges provide a fluid opening action, making this another option if frequent access to the cabinet is needed.

​Metal corner hinges

Metal corner hinges, like concealed hinges, are mounted inside the cabinet and make perfect electrical enclosure hinges with a 180˚ rotational angle. A cabinet corner door hinge contains a pin, which you can remove when the doors are open. This enables you to take off the doors for easier access when maintenance is required.

​HVAC hinges

HVAC hinges are also suitable for electrical panels. Made of die-cast zinc alloy, these are heavy-duty free-swinging hinges ideal for large flush fitting doors for industrial enclosures. Available in different styles.

Locks and latches

If you’re designing a NEMA or IP cabinet, choose electrical enclosure locks and latches with the same rating. Your choice will also act as your handle, with either the key allowing you to open panel doors or a handle as part of industrial cabinet lock or latch.

Installing locks on outdoor cabinet door
​IP65 quarter-turn spring latches

IP65 quarter-turn spring latches are dust tight and help protect the equipment within the cabinet from jets of water. With six different head styles and seven grip ranges to choose from, these quarter-turn latches provide a rubber gasket for better sealing. Your choice will also act as your handle, with either the key allowing you to open panel doors or a handle as part of industrial cabinet lock or latch.

Adjustable compression latches

Adjustable compression latches are also rated IP65, making them suitable as an electric meter-box door latch. A compression latch is ideal not only for sealing against ingress, but also for noise isolation and vibration reduction. This adjustable compression latch is available with an offset cam lock, or you can choose flat or deep cam styles.

​Mini adjustable compression latches

Mini adjustable compression latches, rated IP65, perfectly suit a small outdoor electrical cabinet, electric cable junction box or any application with limited space. With an adjustable grip range, these are supplied with a sealing gasket.

​Flush cup T-Handle latch

Flush cup T-Handle latch is best suited for large-door cabinet panels. Rated IP65, this recessed stainless-steel handle is ideal for hazardous environments that outdoor cable enclosures are sometimes placed in.

Lift-and-turn compression latches

These lift-and-turn compression latches include key-operated swing handles and compression cam latches and have a 90˚ rotation. The slam-action spring-loaded handle consists of a low profile that tucks away when not in use. While not IP or NEMA rated, they work extremely well outside or inside. It’s ideal as a heavy-duty compression latch for outdoor telecom equipment cabinets.

Electrical outdoor cabinet
​Sealing gaskets

Door gaskets and seals

Sealing gaskets create a compression seal for your cabinet door. They clip onto the panel edges to provide additional sealing to fill the space where surfaces mate. Opt for EPDM or PVC material. Both are outstanding as outdoor electrical box gaskets, protecting against the effects of weather and the shock of vibrations.

Gasket tape

Weather stripping tape can also help seal gaps between irregular surfaces. The gasket tape made of EPDM and PVC creates superior barrier protection from moisture and air. These excellent electrical-enclosure gasket materials also resist weather and oxidation and offers conformability and flexibility at low temperatures.

Flipper gasket seals

Flipper gasket seals are an additional seal to enclosure boxes. Typically used on metal sheet, they clip on profiles, offering edge protection and sealing. Use a flipper gasket seal for protection from vibrations and ingress of humidity and dirt. Made of EPDM. You can also opt for a bubble gasket seal, which serves the same function but has a different shape. Also made of EPDM.

Outdoor cabinet top and side panels

Top and side panels

If you’re designing an outdoor wall-mounted data rack cabinet, you’ll only have access through the front door. Instances like these give you the rear panel to work with. You can place the components below on either the top, side or rear panels.

Fan accessories for small cabinets

Mesh fan filter

You’ll need an electrical cabinet fan. Fan filters ensure that clean, filtered air cools the electronics housed by your cabinet. They keep airflow unrestricted by removing harmful particles. Stainless steel is an ideal material for a fan filter mesh sheet in outdoor applications, as it contains corrosion-resistant properties. Metal fan filters are also available.

Fan guards

To prevent debris from falling into your electrical-enclosure fan and causing obstruction, consider this metal fan guard made of steel. Fan guards are essential for protecting the equipment that your cabinet will house. The fan guard shown here is simple to install with a screw mount application.

Fiber cabinets

Fibre-optic cabinets

A fibre-optic cabling installation provides better and faster data than installations that rely on standard copper cables. The only issue here is that fibre-optic cables are more fragile than copper cables. This is why, for example, reducing bend radius is critical. And it’s why you need good fibre cable management in place. But it’s not only about bend-radius protection or fibre-optic cable protection. Running fibre-optic cable also means you have to think about cable routing paths and ease of cable access.

Here are the components you’ll need for effective fibre-optic cable management.
