The typical design of a hasp entails the separation of its two plates so it can be installed on a switch or another lockout tagout device. Once the hasp is hooked onto a switch or LOTO device, you can then push the two plates together in such a way that the padlock holes are all aligned.
Once the padlock holes are aligned, you’ll be able to hook a padlock shackle through each hole. Using hasps and padlocks together is thus easy and straightforward.
