This plug has two round holes, but most people don’t know their clever purpose.

Manufacturing Efficiency and Tamper-Evident Seals

The two holes also serve a practical purpose in the manufacturing and retail process. Manufacturers often use these holes to secure tamper-evident seals or ties to the plug. These seals allow consumers to easily verify if the plug is new and unopened, ensuring product authenticity and integrity. By incorporating these holes, manufacturers can reduce material usage and manufacturing costs, contributing to more sustainable production practices.

In conclusion, the two small holes on your electrical plug, often overlooked, play a significant role in ensuring safety, preventing accidents, and maintaining product integrity. These seemingly minor design features demonstrate the thoughtful engineering and attention to detail that goes into creating everyday products.
