Upgrade commercial door openings with the Vector Hinge Co. 4.5" x 4.5" Ball Bearing NRP Hinge, built for smooth operation, durability, and added security in demanding commercial and institutional environments.

A Non-Removable Pin (NRP) adds another level of security by helping prevent the hinge pin from being removed when the barrel is exposed on the unsecured side of an out-swinging door.

Ball Bearing Construction

Ball bearings between the hinge knuckles help reduce metal-to-metal friction during door movement.

Benefits include:

• Smoother door operation

• Reduced hinge wear

• Quieter movement

• Improved performance under frequent use

• Longer service life in demanding applications

Ball-bearing hinges are particularly well suited for commercial doors that experience repeated daily cycling.

NRP – Non-Removable Pin

The Non-Removable Pin provides additional protection against door removal when the hinge barrel is accessible from the exterior.

NRP hinges are especially useful for:

• Out-swinging doors

• Exterior entrances

• Service doors

• Secure rooms

• Utility doors

• Commercial entrances

• Security-sensitive openings

The NRP feature prevents the hinge pin from being easily removed while the door is closed.
