Hinges are for use on high traffic in commercial construction. These heavy-duty hinges are designed to endure rigorous use, making them ideal for demanding environments where durability is paramount. Hinges are furnished with All Wood Screws (1 1/4" x 12 FPHW) and All Machine Screws (1/2" x 12-24 FPHM) Non Rising Stainless Steel Pin with Button Tips. Commercial Grade Hinges are .180 thickness with a template screw hole pattern. The hinge features an NRP (Non Removable Pin), which is a set screw that is inserted into the hinge barrel and cannot be accessed when the door is closed.
The heavy-duty classification ensures that these hinges can handle frequent opening and closing without compromising performance. This makes them suitable for various applications, from office buildings to public facilities, where reliability is non-negotiable.
The Oil Impregnated Bearing (TA Prefix) are non-ferrous, and self-lubricating bearings that ensure even longer-lasting wear and resistance to clogging, corrosion, and hinge failure.

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:
-
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. -
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. -
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
