Key applications for Access Hardware

You’re designing an industrial cabinet. Among the issues you have to consider are security and perhaps vibration protection and noise reduction. Outdoor utility cabinets, electrical cabinets, machinery, industrial generator parts, HVAC components and data cabinets all need at least one of these issues addressed.

Our range of access hardware solutions can help you with all your requirements, delivering security, controlled access, productive operation and reduction in unnecessary repair costs.

This guide is designed to give you an introduction. We can provide 3D models (CAD files) upon request or offer our single-pack option so you can verify form, fit and function.

IP and NEMA ratings

As a design engineer, you’re familiar with IP ratings for outdoor enclosures and some indoor cabinets. IP ratings – short for Ingress Protection or International Protection – is better known in Europe, while NEMA is usually used in North America. Both IP and NEMA electrical enclosures require access hardware with the same rating in order to maintain their rating.

Both ratings tell you the amount of protection electrical or industrial enclosures provide against the entry of solid foreign objects and against moisture ingress. You’ll find approximate conversions of IP to NEMA ratings in The Outdoor Enclosure Latch and Lock: IP and NEMA Ratings. Below is an example of how NEMA and IP convert. Note, the numbers in IP ratings denote protection from solids and liquids.

Enclosure Type

NEMA IP code NEMA Definitions Solid Protection Liquids Protection
3 IP54 For either indoor or outdoor use
Protects personnel from incidental contact with enclosed equipment
Protects from falling dirt, rain, sleet, snow, & windblown dust, and external formation of ice
5 = Protected against dust
Limited ingress permitted
4 = Water sprayed from all directions
Limited ingress permitted
4 IP65 For indoor or outdoor use
Protects personnel from incidental contact with enclosed equipment
Protects from falling dirt, windblown dust; rain, sleet, snow, splashing water, hose-directed water; and external formation of ice
5 = Protected against dust
Limited ingress permitted
6 = Strong jets of water from all directions
Limited ingress permitted

Here’s an example of how to customize your latch:

Choose your lock type, then decide to specify inserts, housing and the cam lock design to meet your requirements.

Prefer a nylon insert over stainless steel? Want to increase the grip range of your lock?

It’s your choice. If you want advice, our experts are happy to help you with your made-to-order solution.
