The purpose of the NRP (Non-Removable Pin) option in a hinge.

Understanding NRP Hinges

The NRP (Non-Removable Pin) feature is a crucial innovation in the world of door hardware. Here's why it's an essential aspect of secure door installations:

1. Enhanced Security:
   The primary purpose of the NRP is to prevent unauthorized removal of door hinges from the outside. This is vital for exterior doors or any doors where security is a concern. The non-removable pin ensures that even if someone tries to tamper with the hinges, they can't simply remove the pin and detach the door.
2. Optimal for Outward Swinging Doors:
   Many commercial and residential doors swing outward, which means the hinge pins are accessible from outside. This makes them vulnerable to intruders. The NRP feature effectively mitigates this risk by securing the hinge pin.
3. Durability and Peace of Mind:
   With the NRP option, door users can enjoy greater peace of mind. The pin is designed to withstand tampering, offering long-term durability and reliability without compromising on the aesthetics or functionality of the door.

By opting for hinges with an NRP feature, you ensure a higher level of security that safeguards against forced entries through hinge manipulation.

When exploring these options, consider the specific requirements of your project, whether it's for residential or commercial use. Each of these types addresses unique needs, from added security to increased functionality.
